Idepad510s won't boot

Question: Idepad510s won't boot

Hi, i have an ideapad 510s and basically this is what happened, all of sudden the blue "something went wrong screen" and it tries to restart. After which, the lenovo logo appears and after which checking media appears and after waiting roughly about a minute or so the error message "default boot device missing or boot failed" shows up, I tried pressing ok and i chose Windows Boot Manager(LITEON CV3-DE256), I pressed on it and it seemed to start normally untill that blue screen appeared again and I tried the entire process again but instead this time it takes me to checking media .. and sometimes displays checking media failed, i have done this more than 20 times if I recall correctly but it wont just boot, if it does, the blue screen would appear and i have to start the process all over again, at one point the blue screen of error seemed flushed out in colours, i suspect this is a graphic card issue, i really need help quickly on how to fix this, please. Thank you. Lenovo idepad510S

Preferred Solution: Idepad510s won't boot

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

I have a Win XP desktop which had problems with the hdd. The hdd and disk drive were connected to the same IDE bus(the motherboard only has one), the disk set as slave, the hdd as master. The computer worked fine except for errors with the hdd. I purchased a new hdd, and copied all contents of the old hard disk over using acronis migrate easy. In order to do this, I had to disconnect the disk drive, and connect the new hard drive in its place. The cloning process went smoothly and when I disconnected the old hard drive, I was able to boot into the new one. Everything worked fine, but when I connected the disk drive and rebooted, I got the error message:
"reboot and select proper boot device

Hey guys,
just reformatted my PC with Windows XP x64 bit edition,
After putting in my Mobo CD and installing the necessary drivers,
I restarted and got this message:
Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key
I looked around the internet for a bit, and most said to change the boot sequence in the BIOS to the primary drive,
it was already set to the primary drive, so I disabled the 2nd and 3rd boot choices.
But low and behold, I still got the message.
Although, a couple times, I was able to get to Windows.
Then when I restart, I get the message again.
So I'm not really sure what to do.
Thanks to anyone who would like to help.

Answer:Reboot and Select proper Boot device or Insert Boot Media in selected Boot devic

First...system manufacturer and model?
Just guessing...but I would disconnect the hard drive and reconnect it...then see if the BIOS properly recognizes the hard drive.  If it does, then I would try to boot.
I would also enable all boot options in the BIOS...and try to boot from an option other than the hard drive, if you have a bootable XP CD, bootable USB, etc.  Save all changes made by hitting F10.
If the system can boot from an alternate option but not from the's probably a hard drive situation.
If the BIOS doesn't cannot retain the changed settings or you start getting other hardware guess would be CMOS battery needs replacement.

I have dual boot in my laptop with Ubuntnu 14.04 LTS and Windows 7 Home Premium 64 bit. Today after working on Ubuntu I restarted and switched to Windows and as soon as it logged in I noticed the battery was 0%. I thought maybe it was some kind of glitch or something (silly me!) so I just pulled the power supply and the laptop abruptly turned off. My laptop battery is completely dead now...won't charge at all and after that incident when I tried to log back into Windows it showed this error:

Windows failed to start. A recent hardware of software change might be the cause. To fix the problem:

1.Insert your Windows installation disc and restart the computer.
2.Choose your language settings, and then click "Next".
3.Click "Repair your computer."

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

Status: 0xc000000f

Info: The boot selection failed because a required device is inaccessible.

I don't have an installation disc, I tried pressing F8 and none of the options there helped. Ubuntu still works totally fine though. So I'm guessing it is not some hard drive crash and my data are fine in Windows but I just can't boot into it! Please Help!!

Answer:Dual Boot: Win7: Boot Manager Status: 0xc000000f boot selection failed

Are you using GRUB2 as bootmanager and is windows one of the options? Or do you start ubuntu from the win7 boot menu?

Hey guys,
Thanks ahead of time for the help. I can honestly say I'm dumbfounded with this issue and would rather ask for help then hook up my master HD as a slave and force a reformat which would be my next step.

Anyways, here's the background on the issue.

AMD Athlon 64 3700+ OC'd to 2.75ghz
Asus A8N SLI Deluxe Mobo
BFG Tech Nvidia 7800 GTOC x2 (SLI)
Dual Sata Hd's, both the 3gb/s connection. (750gb main/250gb Backup)
Sound Blaster XFI Fatal1ty sound card
Creative modem blaster v.92 dialup modem ( @ dialup)

A few days ago, not quite sure why, but when I booted the comp the graphics card proceeded to tweak out and basically looked like fuzz upon entering windows. Eventually after hard resetting it a few times it'd boot normal. Today, I was running Nvidia NTune utility to find a stable OC setup for my PCI bus and what not, and it rebooted as normal during the process. Graphics card tweaked again, so I did what I know to do and uninstalled/reinstalled the drivers for my 7800's. Seemingly fixed the problem. Rebooted and resumed the OC process and went to watch TV.

45 Minutes later I come back and my computer is rebooting itself constantly. Upon getting the the xp loading screen, it BSoD's and reboots.

So, I try and boot in safemode to uninstall/reinstall drivers yet again. When I press safemode, it begins loading basic drivers. When it gets to SPTD.sys it pauses, locks up, and reboots (no BSoD)

Next step, repair through XP installer di... Read more

Answer:[SOLVED] BSoD on standard boot, safe mode boot, and xp install disc boot


Well, a friend needed me to fix a design for him emergency status in Illustrator CS3, so I went to work troubleshooting.

All signs point to NTFS.sys being corrupt, etc. Which makes the drive unreadable, hence the reboots.

So, I snagged my dads IDE harddrive from his computer, hooked it up as master in my computer and it still gave me the BSoD. I then unhooked both of my Sata Hd's, and ran ONLY the IDE drive. This IDE drive is fine (i'm on it right now on my dads comp to write this). I try and boot my system off just his harddrive and it STILL gave me the BSoD.

Only difference is the BSoD is staying up now on normal boot so I can give you the error.

Error code is 0x0000007B? I believe.

But yeah, the computer is still unable to boot off a good HD even with the bad ones not hooked up.

Now I'm thinking a memory issue? or Video ram issue? Fried GPU/RAM?

AHHHHHH!!!!! i have no idea what to do. This is ridiculous. meanwhile my friend is screwed on his design for a t-shirt i told him i'd do.

The first thing you are going to need to do is to purchase and install a hdd.
Newegg has a Western Digital 1TB hdd for $69.99 plus tax and shipping. 
You will then need to install Windows Home Premium 64-bit.  You can download a ISO image of your operating system here.
You will need to burn the ISO image to a DVD to create a bootable installation disc.

Computer: Dell Inspiron 1525, 320 GB HD with about 2 GB of free space left, 4 MB memory, running Vista Home Premium 32-Bit, SP1, updates current. Just lately, booting from off, Windows will not load, but instead gives me a \Boot\BCD error (0xc00000f)--an error occurred while attempting to read the boot configuration data. I have repaired this error with my Dell-supplied OS disc repeatedly, and each time I turn off the computer it has the same error at startup. I have read that I may have to rebuild the BCD, but I don't know how to do that. Before I check with Dell, who I suspect will just tell me to reload Windows, I need to know how approach fixing my boot configuration data. The computer has had no new software installations, just routine Windows and Trend Micro Internet Security updates, I checked the disc for errors, and a few files were missing or incorrect, and defragmentation has also been performed routinely. Dell PC checkup finds no issues. How should I proceed?

I managed to mess up my Windows 8.1 factory install almost as soon as I unboxed my Y50-70 with a couple of boneheaded moves. I was able to restore Windows from a downloaded USB image from Microsoft and the BIOS Windows key on the laptop. So far so good. The boot is on /dev/dsa1 as fat32. I have a suspicion that the system when installed was in a different location from the factory. The reason for my suspicion is the following. When trying to install Ubuntu 14.04 as a dual boot, Ubuntu cannot see the Windows OS. I have tried shrinking the Windows partition using the windows partition utility. I have also changed the unallocated space from shrinking to ext4 using GParted. Do I need to change the Windows boot location or change the BIOS boot type to get Ubuntu to see it should install alonside Windows?

I have a dual boot installation with Windows XP and Windows 7 on the same drive with two partitions. Both work just fine.

However most times that I boot from a cold boot, I get NO Boot options menu, just a blank screen and the hard drive light glows red, but it doesn't really seem to be doing anything.

If I press the reset switch, everything works just fine, the computer reboots, I get a boot options menu for selecting the operating system and either one boots up just fine.

If I shutdown the machine for any period of time, I'll get the blank screen until I do a hard reset.

It seems like the boot loader is not finding the ini file with the options, but only on a cold boot? Any suggestions would be appreciated.

Hi wjason777. Welcome to the TenForums @wjason777

Normally I don't comment in BSOD section of forum.

When you installed windows did you have other drives attached? I would re-do the clean installation with only your primary boot disk attached.

I would also get a fresh copy of windows using the media creation tool and just leave it on USB Key.

Here is the clean install tutorial.

Clean Install Windows 10

If you only have your windows and programs on boot disk I might be inclined to delete all partitions and let windows rebuild, think it is step 13 in tutorial. Ensure your data is backed up.

Have one of the mods move thread to Installation section.

Hello Lenovo Forum!This is driving me mad. I bought a SATA-to-USB3 Adapter to connect my SSD and HDD from my old computer and boot from them (I want to use the Linux on it). Yet I can't figure out how to do that. Secure Boot is off, Legacy Boot is on and yet - everytime I choose the drive in the boot menu, the screen goes black, there is a short drive access, and then I'm back at the boot device menu. I don't really know what to try now. Reimaging like most other threads here suggest doesn't help in that case because it's not a simple installation medium. What I tried aswell: Attaching the Adapter via a USB2-hub to check if there might be an issue with USB3 support. When plugged into my friends X230, both drives boot up perfectly fine and he can use them just fine. Any kind of help is highly appreciated.Kind regards,Iriya EDIT: Here the BIOS Options which I think are somewhat useful:Config TabUSB UEFI BIOS Support - Enabled (Tried turning it off, didn't helpSecurity TabSecure Boot: DisabledPlatform Mode: User ModeSecure Boot Mode: Standard ModeStartup TabUEFI/Legacy Boot: BothUEFI/Legacy Boot Priority: Legacy FirstBoot Mode: QuickRestart TabOS Optimized Defaults: Disabled

New to this forum, sadly my laptop won't boot....I'm hoping I can get some insight here.
I get the black screen with the following messages:
"PXE-E61: Media test failure, check cable
PXE-M0F: Exiting Intel Boot Agent.
No boot device found. Press any key to reboot the machine."

I can get into BIOS and run diagnostics followed by the prompt: "Success, all tests pass.".....but system won't boot.
I searched and searched the internet and tried various things but no change.
I removed and reinstalled the hard drive twice, no change.
I made sure the HDD is first to boot order in change.
If anyone can point me in the right direction I would certainly appreciate it.
Thank you in advance.

Press F12 at powerup - boot to the Dell diagnostics and run an extended test on the hard drive - this will take a couple of hours (not just the 10 min or so the quick test did).  It'll likely show a bad drive.

My dad just bought a new laptop and gave me back my ancient VAIO T150 that I gave him 2 years ago. I was going to format it, and keep as backup laptop, unfortunately BIOS has a password which I know my dad did not put in. Chances are I set up the password years ago, I went through every possible combination that I could have used still without luck.

I gave up on that route, and simply ran windows install from within windows, the problem is that windows installer does not let you format the drive when you start windows install from within windows, saying that temp files are stored on the hdd. Windows recovery console is also of no help, as it does not let you execute setup.exe

I could pull the drive, format it, install DOS on it, put it back in, and then get the installer going, but as it is a subnotebook, disassembling it is a pain.

Does anyone have any idea how to run windows setup installer when you are locked out of bios boot order options, but have full access to the actual machine? Lol, no the laptop is not stolen.

Answer:Changing windows XP boot manager to boot from CD. [cannot boot from CD directly]

You've got a couple of options.

First, you can try to force boot to the CD. Lots of computers allow you to press a key to modify the boot sequence for that boot. Try hitting keys like F8-F12 and see if any of them bring up a boot menu. If that doesn't work, try to cancel any GUI boot screen to see if you can find what key you need to press.

Your second option is to clear the BIOS password. You might be able to get away with flashing the bios to a new/old version, but there are utilities out there that will help you clear the BIOS password. I've never actually had the need to use them, so I can't comment on how good they work, but they shouldn't be too hard to find.

And I only see that BSOD when I disable automatic restart. The stop code is 0x000000ED (0x86403130,0xc000009c,0x00000000,0x00000000). I get the blue screen (momentarily) on all of the other F8 options.

When I boot using the Vista disk I get the msg 'Windows is loading files...', then I get what looks like the bottom part of the XP splash screen - the little bar with the green dots moving from left to right (was that part of the Vista start, as well?), then eventually the screen goes black..... and stays that way. Although after about 30 seconds the mouse pointer does show up - and its moveable. And the keyboard lights up properly on Caps Lock and Num Lock. But nothing else.

I did try booting off an old XP disk, and it did take me to a place where I could delete the partition.

Should I try that, and then try the Vista disk again, or should I just go ahead and install XP (although I would have that pesky product key to deal with)?

I somehow feel that if I could only get to a C: prompt I could do a fixboot

Answer:Vista will not boot - Unmountable Boot Volume - Won't Boot from Disk Either

and I'm not talking about a good answer. ANY response at all would have been appreciated.

My original post, titled Vista will not boot - Unmountable Boot Volume - Won't Boot from Disk Either seemed like it would be the kind of posting that would have elicited some response - Can't boot normally, in safe mode, or last good configuration. AND, can't boot from a genuine Microsoft Vista Home Basic disk.

But nothing.....

So I inserted an old HP Windows XP OS CD into the machine, and booted to the recovery center, where I selected to install XP. I formatted the drive, and then ejected the disk. I then put the Vista disk in, and booted from it.

Presto, it worked. This time it actually took me to the Vista Repair / Install page.

I deleted the partition, entered the product key and re installed Vista.

It is now working beautifully.

Thanks for your help.

Answer:Can't boot my Tablet. Windows Boot Manager boot failed.


Welcome to Ten Forums!

Assuming the Linx tablet does not support 32-bit legacy BIOS mode, and that the Windows version you are trying to install matches the tablet's architecture (64-bit or 32-bit).

As far as I know, to repair the EFI Bootloader in Windows 10 normally you need to get the tablet to boot from the USB recovery media and get to the Advanced Options screen to open the command prompt.

However, have seen where Easy Recovery Essentials, (by Neosmart) has helped in some cases:
Fix UEFI Boot: Fix for Windows 7, 8, 8.1, 10

If no luck with ERE, is there any possibility of contacting Linx for some guidance?
Sometimes these support crews have to be called (if phone number is available) in order to get any kind of help.

We link to tutorials so you'll have illustrated steps for a specific suggestions. It's one of the main reasons we are the top tech forum on the web.

I would not move User folders as we've had feedback indicating unintended consequences. Much easier to copy your User folders to the HD data partition, rightclick each to add to the related Library - Include a Folder - Windows 7 Forums. Keep the emptied C user folder in Library so you can see if anything lands there and drag it over to data drive in same window.

Install most-used programs to C, if space gets too tight uninstall and reinstall lesser used programs to data drive.

To save space you can set paging file to 2gb: Change Virtual Memory Paging File.
If you don't rely on it you can turn off Hibernate in Power Options, though it is perfected in Win7. These are trade-offs that must be decided with a small SSD.

Here are customized install steps for you:

Unplug all other HD's and peripherals,

Check for a BIOS update. If none boot into BIOS setup, reset to defaults, save changes. Next if an EFI BIOS, enable Legacy BIOS, set DVD drive first to boot, SSD second. Then set SATA controller to AHCI. Save changes and Exit.

I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.

the boot menu, Windows 8 starts to boot without difficulties.
How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?

I have an XPS 8500 that will not boot normally. It was running fine and all of a sudden came up with the message "Reboot and select proper boot device or insert boot media in selected boot device and press any key". I have figured out if I go into BIOS first the PC will boot up but is very slow in doing so. I googled the issue and found something telling me to default the BIOS. I did this and it booted once. Trying to decide if the HD is out. I ran diagnostics and it does not see a HD. But if that's the case why does it even boot after going into BIOS. I am running Windows 10 Pro. I updated Windows 7 Pro. I am a strong believer in Dell and find it hard to believe that a HD would go out after only 4 years. Any help would be greatly appreciated.

Usually when I see this error its the Power supply, or and bios issue. Anyone have any Ideas. I can actually boot to windows but the computer shuts down in about 20 min and give that error. I am use to seeing that when it will not start, but it starts and stays on for a bit but not long enough to save stuff. I even tried to reload it and it wouldn't let me. I am figuring its the hard drive. Any Ideas

"reboot and select proper boot device. Or insert boot media in selected boot device and press any key.

Answer:"reboot and select proper boot device. Or insert boot media in selected boot device

First of all, no one has any idea what we are attempting to diagnose. Post ALL of your exact system specs; ie exact mb, exact ram, exact video card, etc, etc. If this is a big box system, then post the exact brand and model# If you have a service tag# post that as well.

Note do not post "500W pw supply" Post the exact brand and model# Do that for all of your parts.

Hi There!
I am having a problem starting my PC! I have to start it in the boot menu under the RAID option. If I do not do this a message saying "Reboot and select proper boot device or insert boot media in selected boot device and press a key.." comes up, and just keeps popping up regardless of what I press! I would try using my boot disk but for the life of me I can't find it, and as windows 7 was already installed on this computer when we got it 3 year ago, I can't accurately recall if it came with one!
I am no expert on BIOS, but I have read other problems similar to this one, and know that if I don't have the boot disk or the OS disk, I will need to know that at least. So my boot sequence is as follows:
Boot 1: (Hard drive)
Boot 3: USB: Generic-Compa
Boot 4: Lan

I am curious if the (Hard drive) is the issue. The BIOS tells me that anything in parentheses is disabled from corresponding type menu. But I truly have no idea how to change that. Which brings me here.
If anyone can offer any help to this, I would greatly appreciate it.

HiYou will have to give a little more information.What is the make and model of the computer?If it isn't a brand name what make and model of the motherboard.Or you can post a Speccy that will give that information.[ Go to Piriform's website, and click the big button.

Next, click Download from (the FileHippo link requires an extra click). Or if you want to use a portable version of Speccy (which doesn't require installation), click the builds page link and download the portable version.

You will now be asked where you want to save the file. The best place to put it is the Desktop, as it will be easy to find later.
After the file finishes downloading, you are ready to run Speccy. If you downloaded the installer, simply double-click on it and follow the prompts until installation is complete. If you downloaded the portable version, you will need to unzip it before use. Right-click the ZIP file and click Extract all. Click Next. Open up the extracted folder and double-click on Speccy.
Once inside Speccy, it will look similar to this (with your computer's specifications, of course):

I'm having a problem with booting my laptop - but only when cold-booting.

Never heard about this problem before. I can reboot just fine, and if i acces the BIOS and just go straight on exiting, not changing anything - it too boots windows normally without any hitches.

How is booting different from cold-boot to rebooting or through BIOS? I've been toying around with EFI boots, but everything [should be] reverted and i used my windows disc to repair the boot sequence. After the BIOS splash it just lingers and the "starting windows" gui doesnt appear.

Edit and edit2: I've now tried for a couple of times to let it sit, and it does boot up after about 4 minutes consistently. It goes like this:
I press power on. After,
3 seconds the BIOS splash comes on.
7 seconds the screen goes black.
4 min 0 seconds the screen turns off, then immediately turns on again with a black screen.
4 min 3 seconds the BIOS splash reappears.
4 min 7 seconds the "windows starting" gui comes on.
4 min 25 secs windows is booted up and responsive.

So the Black screen is consistently just about 3 minutes and 53 seconds. All BIOS settings are properly set to boot from HDD. No external HDDs or FDDs connected. Even removed the excess drive letter assignments in windows to be safe.
Satas in AHCI for the OS-SSD (and a spindle for storage). Booting from spindle drive is disabled in BIOS.

Hi all!
Hope you can help me with this..

I have a multi-boot setup, two partitions with XP.
On booting I get prompted for a system disk (in Norwegian text).
To escape this prompt I have to find a bootable CD and then eject it on the prompt. Then I come to the normal dialog with choosing operating system to boot from.

So, it's not life or death, but rather annoying.

I've checked out the issue and found that the bootfile: "NTLDR" has a switch named /minint .
Se: NTLDR - Wikipedia, the free encyclopedia
I've used "The Ultimate Boot CD" and then wonder if this Cd-based OS has turned the switch on?
Could this be the case? And how can I turn it of?
And if it's not? Any ideas?

Thanks all!

Answer:Boot issue, multi-boot, Ultimate Boot CD

You could try doing a repair install from your XP CD. Just boot to the XP CD and choose to repair install rather than a complete installation.

You could also try booting to the Super Grub disk. It has an option to fix your Windows boot loader.

I'm doing an upgrade on a computer with a new: PSU/Mobo/RAM/CPU but I get this error upon start up. I've verified that the IDE cables are plugged in correctly and I've tried all the jumper settings on the hard drive but no devices show up in the BIOS. I've set the boot order as CD/DVD, Floppy, Hard drive. I've tried two sets of IDE cables but to no avail. Any other solutions to this problem?

Answer:reboot and select proper boot device, or insert boot media in selected boot device

Make certain your IDE cables are not just plugged in correctly but their also correctly placed. The side of the cable with the color strip is generally closest to the PSU plug up.
The boot order with your OS in your CD drive on boot should be CD - HD and then Floppy. Keep us up to date as to what's happening. There's a lot of folks willing to help. Jazz
I should ask what settings you've left your HDD on with the jumpers? What setting is you CD on with the jumpers?

Today I went out and bought a WD1600JB 160GB hard drive. I installed the hard drive and it was recognized by the bios but not by windows.

I was entering my correct password (i made sure) and it wasn't logging me in. This has happened a few times before, and everytime it was fixed by rebooting.

XP is a bootable CD. First off, enter your BIOS at boot up and change drive priority so that your CD is looked at before the HDD. Insert XP CD and follow instructions. It will get you to format/partition your HDD. Follow the prompts. You don't need a bootable diskette so leave the 3 1/2 drive empty.

I have absolutely no idea what I'm doing. I tried to get my desktop computer set up for the school year, but found myself with a Blue Screen Error every time I would turn it on. I had this problem on my laptop just weeks earlier, and when I turned it into the shop, they informed me that it was caused by corrupted RAM. So, instead of wanting to pay another $300 to get the desktop fixed, I chose to take out the RAM myself. Bad idea...

For some reason, the RAM appeared to be melted or scratched away a little bit at the bottom (gold part that goes into the slot). So I took that RAM out. Only now when I turn on the computer, it gives me a screen saying "reboot and select proper boot device or insert boot media in selected boot device". I go into the Boot Menu, and it gives me two options, both bringing me back to the same "reboot and select proper boot device or insert boot media in selected boot device" message. I tried taking out a RAM drive from a different desktop computer and putting it into the one I'm trying to fix, but then the monitor wouldn't read the computer being on. I switched monitors, but to no avail. I switched RAMs from other computers, but that doesn't work either. I can't afford to take this into the shop or buy new parts for it, but I really need it for school. I don't even care about it running slower or files on their disappearing forever. I just want my computer to run.

Answer:Reboot and select proper boot device or insert boot media in selected boot device?

I just want to be clear here (point form is sometimes good)

PC Bluescreens
Removed Ram (looks to be physically faulty, gold plate scratched off)
Turned on computer (not sure if you re-inserted the original Ram here again)
Now cannot find HardDrive boot sector
Tried Ram from another (unknown) computer (Note: Ram specs may be incorrect)
Would not POST (Power On Self Test)
Put the original Ram back in
From here, I don't know what's happening, probably not Booting again (ie your long heading)

This is what I recommend (even though I'm still a little unsure where your at!)

Remove the Ram (By the way 1 or 2 Ram Cards?)
Blow out (either compressed air in a can, or just using your breath) the Ram slots
Re-insert the Ram (you usually just need one in there to test with) Note: They click in
Unplug the cables going to your HardDrive (HardDrive end and Motherboard end)
Re-insert the HardDrive data cable (securely)
Do the same for the HardDrive Power Connector (pull it out, then push it in with a little force)
Now do the same for the CD/DVD Drive data and power cables (you can even just leave these cables fully out)

Turn on !

Hey guys, quick question for you.. Now my friend has this error: "Reboot and select proper boot device or insert boot media in selected boot device and press any key?" and I've been trying to help him for a while with it. He told me he took out his hard drive and RAM for some reason, then a little bit later put them back in.

And now all of a sudden hes getting this error. He has an HP e9300z computer and I guess has a gaming keyboard and mouse plugged in, which also don't work. So he can't get into his bios to check boot order. He also doesn't have access to a linux live CD or a repair disk CD. He is using windows 7 as well.

So if anyone has any ideas or had this happen to them, any info would be awesome!!

Answer:Reboot and select proper boot device or insert boot media in selected boot device...

He may need to connect a PS/2 keyboard to get into the BIOS Setup (assuming his PC has a pair of PS/2 ports for mouse & keyboard). Some computers don't respond to USB keyboard input for BIOS access. Mine is like that and it's a new PC - good job I kept my old PS/2 keyboard because they are difficult to find these days.

Since you installed new ram and had no issues before that is where I would start, run Memtest. If it shows any faults whatsoever the ram has a problem. New items can fail during initial burn in, Memtest is free and has good approval ratings here and on other boards.Look for "free down load on the left"

The problem is that it won't boot up. After the intel screen loads it shows:

Fastrack... Bios Version 2.00 0.33... then
"Scanning IDE Drives" then it turns to "No Array is defined...
Press <Ctrl-F> to enter FastBuild(tm) Utility or Press <Esc> to continue booting"

That's no problem but I can't press F8 or F2 or anything like that.

Pressing CTRL F is useless because i don't have that fast build thing, and when i press ESC or just wait a short while it turns to a black screen and all it shows is "Reboot and select proper boot device, or insert boot media in selected boot device and press any key" if i press any button it just shows that again but another row and it makes a click sound.

Problem happened after power shortage. No floppy discs or usb devices inserted at the moment. There could have been a CD in there but probably not.

I cannot seem to figure out what's wrong with this computer.

The hard drive is a 500GB SATA. The hard drive is clearly plugged in (both cables plugged in)... Since it's a SATA, doesn't need a pin.

I took this hard drive from a working desktop and put it in a customized desktop... The thing is, it's a partly customized desktop, just a different DVD drive, hard drive, and graphics card. The motherboard and everything else is the same as was in this computer.

Anyways, the hard drive is empty and was working as a slave, simply to put things on it. Now, I'm trying to put it in a different desktop and it's simply not working. Both the DVD and HDD are recognized as the Primary SATA master and slave. This seems correct to me.

Welcome to TSF

That message is indicating that it does not see the hard dive to boot to it. Odd the BIOS doesn't see the hard drive or the optical drive. I'm assuming Windows 7 ran successfully prior to the wipe and reinstall? Can I ask why you reformatted in the first place? What driver did it say was missing? Did the install halt at that point requiring a reboot or did you just reboot because of the missing driver message? Make sure you have no USB devices attached to the system as it may be trying to boot to USB device. Also you may want to change boot order in BIOS

Hi everyone,

I've been encountering a problem where upon booting I receive the following message: "Reboot and select proper boot device or insert boot media in selected boot device."

To provide more context, the computer that is showing this problem recently received a hardware upgrade. I figured out that my PSU was insufficient for some of my current tasks, and decided to upgrade my power supply. Since I decided to do so, I thought of upgrading the video card and the RAM (since it was a rather old computer as well).

Upon installation, I received the following message. The OS is Windows 7.

Boot into the BIOS, and check your boot devices. It maybe trying to boot from a USB device, or CD.

To enter the BIOS, reboot system then press either the Delete key, or maybe the F2 you will see a message about which key to "enter setup"

You have removed the "Master" drive which XP booted to.
Now you will have to make the 2nd drive into the "Master"

Connect this 2nd drive using the connector which was used for the drive you removed.
Then change the jumpers on the drive to master.

Answer:"Reboot and Select proper Boot device or Insert Boot Media in selected Boot device.."

The "DHP watchdog violation" could be caused by any number of things, typically within the OS. Which is a non-issue now since the PC won't boot.

What error do you get now when you try to boot? If it's the same or similar to "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key", then it sounds like the HDD (which is the primary boot device) cannot be found. Which typically indicates a HDD failure, but could also be just a loose/faulty data or power cable.

Enter the BIOS and verify if HDD is recognized properly, and if so, verify the boot order.

So I have been trying to get my computer running for a few days now. At first it wasn't booting at all, it would be a black screen with a blinking cursor. I have cleared cmos a few times, turned psu off, drained charge from psu, turned psu back on and got it working that way for about 10 minutes, then it crashed. Ever since then I can't get it to get running again. I think it says something about "fatal error" and then goes on telling me to boot into safe mode to remove any new hardware. Is it a hardware problem I'm having? If so, I'm screwed, too broke
The best I can get is the screen where it says run windows normally or run in safe mode. But it will just crash on either option I pick. And when I try to run from the dvd drive with my windows 7 disc it's just a black screen with a blinking cursor.
I'm not sure what to do...ugh I feel like it's something really simple to fix. I left my computer sitting for a few months and havn't tried to boot it until recently, so I don't remember if I put any updates on it or not.
I tried running system launch repair and it crashed in the middle of that, now it's just going back to booting to a black screen. Do I just keep clearing cmos, my mobo has dual bios, so the backup bios isn't corrupt. I'm using a gigabye mobo.

Answer:Can't boot, boot into safe mode or boot from dvd

And most of the time it won't even boot at all, it will just be a black screen.

In order to get my laptop running I have to press F10 at the boot, which brings me to a screen that says:

edit windows boot options for: windows 7
path: \windows\system32\winload.exe
partition: 3
hard disk: 350f350f

In order to boot, I have to erase the text:
After that I can boot.


Answer:Won't boot unless I use "EDIT BOOT OPTIONS (F10)" at boot screen

Hi, welcome to the forums

You could try checking the 'Environment Variables' options...

Click Start then right-click Computer and select 'Properties'. From there, click 'Advanced system settings' followed by the 'Environment Variables'. Have a look in the lower box to see if those exact options are there. If so, you should be able to delete them.

I cannot guarantee the effect of this as i've not had personal experience with the issue you're explaining.

I just put together a PC from scratch and when i start my computer it says:
reboot and select proper boot device or insert boot media in selected boot device and press a key.

I put in a copy of Windows 7 Home to boot, and it just continues to say that when i restart/press a key.

Some Info that might help:
The computer does detect my cd/dvd drive (checked through BIOs)
the windows 7 cd does work (tested on my laptop)[also, it is not an upgrade disc]
the cd/dvd rom can run this cd that came with the motherboard, so i know the cd/dvd rom is working.

What I have done and tried:
made sure cd/dvd is on boot first
changed from SATA to IDE connection through BIOS, also tried RAID and AHCI settings.
tried all the ports on the SATA slots with both 3gb and 6gb sata cables on the motherboard

Western Digital SATA Hard Drive
Samsung 22X DVD burner SATA
ASUS P8Z68-V LX LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS

Please help as I have no idea why it won't install the Windows 7 OS. I currently do not have any other OS.

Answer:reboot and select proper boot device or insert boot media in selected

Extract the DVD ISO using Imgburn or download another, write to flash stick using Universal USB Installer with Win7 in dropdown menu. Boot under USB, REmovable or HD's using one-time BIOS Boot Menu key with HD set to boot first in BIOS setup.

The disk are all the same: upgrade, full, retail, OEM. It is the key which determines which version will activate.

Welcome!I'm writing because some serious problems with G580 (59-346104) occured.I've decided to change my C (Windows8_OS) pearition size (850 GB is far to big ammount of space for system files only, I need much more space for my files at another partition). I used the AOMEI Partition Assistant Home to resize C to 150 GB and after that I assigned the 250 GB/each of my 3 new partitions which I need for my files. After applying changes, restarting and resizing the space, AOMEI told that it's required to restart for further resizing process. When computer finished the loading process, the blue screen appeared (with " ") that says "system encountered problems with boot-up and will be re-run, check Inaccessible boot device error" (I don't remember the accurate message but such is the sense of) and so he does but after another restart this message apperas one more time and so on. I've tried to start a recovery but when I run computer with NOVO button and afterch choosing recovery, the system says "Lenovo recovery system boot failed" and then computer starts the "normal" boot proces (which lead to the problem described above).As soon as I know (at least I guess so) where is problem, I have no idea how can I repair this.I'll be very grateful If someone will help me.Gaclav

Answer:Inaccessible boot device and Recovery system boot failed after resizing partition

Hi Gaclav,
Thanks for posting and welcome back to the Lenovo Community,
I?d like to confirm to you that the recovery won?t be working more as you?ve performed resized for the partition and changed the Hard disk size which cause the recovery to be corrupted,
And the only way to get the recovery the system back will be contacting contact support and am afraid to tell you that it would be billable repair at the service center:

Hello everyone

I have a Samsung laptop using Windows 10 and a couple of days ago a blue screen with an unmountable boot volume error showed up after booting, saying the computer would be restarted.After restart a loading recovery option message shows up with the samsung logo and then just a black screen appear and stays like that for hours.

After doing some research I downloaded the Media Creation Tool and uploaded it to my flash drive so I could boot using it and access the advanced option menu through the installation window. After that I plugged it in my laptop and tapped F2 until the BIOS menu appeared. I disabled Secure Boot and selected UEFI OS for OS boot selection, after restarting it again I now tapped F10 and a list with boot options showed, I selected my flash drive and in the first try a windows installation window appeared and I could open the advanced options menu and tried to use the command prompt to make a drive check up and restore as the instructions I found to solve this problem suggested,but the command prompt didn't start and there were just a frozen blue screen. I restarted the computer once again and this time I was going to follow the other way to solve it using the restore option in the advanced option menu.

Although, when I tried to access the menu again, it didn't work, I just got a black screen after the windows logo shows up for a few seconds and everytime I try it happens over and over again.

I am unable to use on my Windows 7 Startup (Notebook NB520), the system's uninstall program to uninstall - a malware/virus.

I have searched on various forums for help and have tried running the malwarebytes anti-malware program which reported the virus files and according to the program has removed them. However I am still unable to uninstall

I found another tool ComboFix but this requires me to run Windows 7 startup in 'safe mode'.

I have 2 questions:
How to I invoke safe mode boot of my notebook?
Has anyone successfully remove or uninstall

Many thanks in advance.

Answer:NB520: Windows 7 Startup - how boot in safe mode boot and uninstall failure

As far as I know ?Safe mode? option is available if you open ?Advanced boot options? and you can do this if you use F8 at start-up. Have you already tried it?

Power your notebook on and press F8 several times.
To be honest I don?t have experience with this ? but if you will be able to start notebook in safe mode try to roll back OS few days back to see if the problem persists.
It helped me to fix one similar problem.

maybe it will help you.

Good luck.

Hello dear sirs,

I helped a friend replace his MB after failure, exactly same MB only new version (2 .1 not 2 - Gigabyte 970A-DS3P) He has a dual boot and Win 8.1 works fine but Win 7 doesn't. Repair doesn't resolve problem. Have looked at various fixes including Command Prompt Dir fix and Paragon software. We are concerned that re-installation will overwrite valuable files. I was wondering what you would advise, we are assuming that a re-installation will probably be needed but would appreciate some advice as to the best course of action.

I have a Satellite L645 I put together 4-5 months ago from the wreckage of it and a Satellite P745  Next, will be learning if swapping the CPU from P745 to the MOBO of the L645, but that will be another day

I recently did a number of repairs on several PC's/Laptops that I restore/refurbish/rebuild to provide inexpensive units to those less financially fortunate.  After 30+ years in the IT industry, and now retired, I can return to computers as the hobby it began as.
While doing this latest bunch it appears I picked up a virus either from one of the harddrives in the wreckage, or from the online hunting & scrounging for parts, drivers, apps, etc.
WIN10 began, during booting up, telling me I needed to allow the Automated Repair to run, then changed its' mind and said to use the Recovery Media to repair the system.  I tried to force numerous incomplete boots to cause the options menu to appear, but to no avail.

The errors progressed to the "a required device is missing or not accessible" when trying to boot from proven USB Recovery AND USB Win10 Install media.  The system tries to boot from the WIN10 DVD boot disk, but after a long wait, that too, fails.
These are the various BSOD screens:

I had a problem with the SATA-HDD, and formated and installed windows on a different computer, everything works find on the other computer, but when I moved the HDD to the right computer, when the HDD is supposed to load windows, this message appears: Press <ESC> to boot 6 ... 5 ... 4 ... 3 ... 2 ... 1 ... And after that, another message appears: Reboot and Select proper Boot device or Insert Media in selected Boot device and press a key.

I don't got a clue to how to solve this problem ... why won't windows load? ... Should I maybe re-set the bios?

Answer:Functioning HDD, receives message on boot: reboot and select proper boot device.

I have this same issue. I loaded WINXP on a sata drive then swapped MB / CPU/ ram. Now every other boot the system does not detect the drive (bios does not see it) then it won't load windows obviously. If I reset a few times it might come back - might not. Drive is good - its like the cmos is not having time to recognize drive? Will boot up pre delay fix this?

Problem with Diskeeper 2008
When trying to do a boot time defrag using diskeeper 2008 I get the following message:

Some argument was unrecognized or conflicting, boot-time not running...

The defrag is then skipped leaving my MFT and Paging file badly fragmented
I?ve Googled but can only find one post (That?s right only one post on all of Google) that mentions this error message but no solution, although I did follow a link that hinted at a possible regedit solution.

The possible solution was:
Go to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager" and remove the string [the name referenced in the message on system startup] from the BootExecute value.
Under normal circumstances only the following would be present:
autocheck autochk *
For Diskeeper it would look like:
autocheck autochk * autocheck AUTONTFS C: PAGE=KEEP DIRS=NONE MFT=MIN

I?ve checked BootExecute in the registry and the string I have reads:
autocheck autochk * autocheck AUTONTFS C: PAGE=MIN DIRS=NONE ENDPAUSE MFT=MIN
I?ve tried to modify string so it reads:
autocheck autochk * autocheck AUTONTFS C: PAGE=KEEP DIRS=NONE MFT=MIN
But after attempting yet another failed boot time defrag I checked the reg only to find that PAGE=KEEP had once again become PAGE=MIN.
I also tried with default autocheck autochk * no luck there either.

This is obviously not a common problem (YET).

Followed the advice of some other posters and I did the following:

2.) Installed my new HDD

4.) Loaded up GParted; Cloned my Partition from 250GB to the 1TB.
5.) Turned off computer, removed old HDD.
6.) Turned on computer, got this error.

Apparently this means that the computer cannot find an OS. If I cloned the HDD, why can it not find the OS?

Any help?

Answer:Upgraded my 250GB to 1TB HDD using GParted. Intel Boot Agent: No Boot Filename Recieved! Help!


I guess your HDD is not bootable...
I mean first format your HDD, set the patitions you need, set the wanted partition as primary and active, load your 250GB.

Well just thought...;
check the settings of your HDD, does your Jumper is in "master" position (check the diagram on the HDD if you are not sure) and the second point if you have Connector make sure you do not have 2 master on the same map (your DVD player and your hard drive for instance) .

Hi a couple of months ago my system crashed, windows 7 wouldnt boot, and I misplaced my installation disk. I had the problems several times since obtaining the computer several years ago. (Lenovo IDeaPad y450). I attributed the problem to what I believed was a bad hard disk, so I replaced it with a refurbished model.
I installed Ubungu 13.10, and it worked well ever since. I later located my win 7 disk and created a dual boot. Windows worked very well for several months until it stopped starting up last week. It would get to the black windows screen, where it says starting, and usually get stuck there. I would get fed up and turn it off after half an hour. Once it was as the screen and it later started the checkdisk program and found no errors. Another time it finally got into windows after a very long loading time, and it seemed to work fine, until the next time I restarted windows. It just went back to the loading windows screen.
I formatted the windows partition through GParted in Ubuntu, and tried the installation disk, and it would get stuck at 0% in the "expanding files" sequence. After an hour of hoping something would happen I got fed up and forced it off again.
Not sure what to do from this point. I have read other posts and it has led me to think that the issue could possibly be bad RAM or an issue with BIOS. But, Ubuntu has been working fine, while Windows has simply been freezing at any attempt of a startup.

Answer:Win 7 , Ubuntu dual boot, windows wont boot, startup disk doesnt help

It could be that the HDD has a bad sector in the Windows partition, or that the drive is actually failing. If there is a utility in Linux that tests memory, I would run it.

You could also use Memtest86+. It runs from a CD/DVD. Let it run for several passes to rule out bad RAM.

Answer:T440s: Boot Issues - Boot Menu doesn't work, System can't restart

Problems #1 and #3 sound like they may be BIOS problems.  Can you check to make sure you are using the latest BIOS version here?
#2 sounds like a timing issue.  BIOS will only wait so long for boot devices to become available.  if your external DVD drive takes too long, then it will be excluded from boot.  One thing to try, turn the system on and then press Enter (instead of F12).  This will bring up the Startup Interrupt menu, where you can press Enter again to pause the timer.  Wait 10-15 seconds for your DVD drive to initialize, then try pressing F12 to see if it shows up then.
For #4 are you using the Lenovo preload or your own install of Win8?

Hi guys,
I have a lab with 40 Dell OptiPlex 9030 AIO (touchscreen) desktops.  These computers all have up to date BIOS firmware.  They are running in UEFI mode with a well tested Windows 10 image, as are all of our labs.
The problem that I am running into is that these computers randomly, upon reboot, will enter the one-time boot menu screen instead of booting into Windows.
If I reboot the entire room, 2-6 random computers will enter into the one-time boot menu.  At that point I can either reboot the computer, or choose the Windows partition to enter enter into Windows.  The lab with this particular model of AIO is the only lab that is affected.  The computers that behave like this could be any of the 40 in the room, and the problem does not consistently happen.  It seems totally random.  When affected, the computer will reboot to the Dell logo screen, then the yellow Preparing One Time Boot Menu text will appear and they'll get stuck here.
I have not been able to dig up any potential causes to this problem.  I've thoroughly looked through the BIOS options, and I cannot see any settings that could be causing this to randomly happen.
This is a really strange problem that I have not encountered previously.  Any insight that you guys have would be really appreciated.  Please let me know if additional information would be helpful, I would be happy to provide it.  Thank you!

I own a Asus N71Jq Series laptop. I was browsing the web. The laptop crashed. When trying to reboot, the "Starting windows" would appear, together with the big Windows logo. I could reboot in normal mode and in safe mode. I chose for safe mode, to no avail. After this, the screen went black and all I could do was move the white cursor. I tried rebooting again and again to no avail.

I picked up my Asus User manual, and it told me to press [f9] during the booting of the laptop. This allowed it to use the Recovery Partition. To no effect.

I'm trying to do a fresh install of Windows 7 Ultimate 64bit but i can't get the installer to load.
I have access to a Xubuntu install and a OS X install.
The original hard drive Windows 7 was installed on stopped working completely. So, I've bought a brand new one.
I followed the steps I did the first time I installed Windows 7 - converting the iso to and img with OS X's hdiutil and the dd command to burn it to a USB.
This time I would just get a "please insert proper boot media" error.
I went to my Xubuntu computer (it's used like a chromebook - i'm not a big linux guy) and tried WinUSB.
These USB keys lead to a screen that had a flashing underscore a few spaces from the top of the screen.
It dawned on me that the first thing I did when I installed windows the first time was update the bios. So I tried flashing a few different BIOS versions, but none of them made a difference>
I really need help - I can't think of anything else to try
Thank you very much!

Answer:Cannot boot into Win7 installer. "insert proper boot media" and "flashing unders

In my experience a blank black screen with a flashing underscore means that the computer cannot find a bootable drive.
If you are trying to boot from a memory stick, go into the BIOS at start-up and make sure that 'USB drives' are the first item in the boot priority list, if you are booting from a Windows DVD, then make sure that your optical drive is first in priority. This may well solve your problem.

Well, I really should have left well enough alone. But I'd been running 1.15 on my P70 (with no problems) and decided enough time had gone by that the latest 1.21 update was probably stable and usable, and should be problem-free.
Unfortunately, now that I've updated the BIOS (successfully) I can no longer boot. The process just hangs at the "press ENTER to interrupt the normal boot process".  ENTER doesn't work, nor does F12.  Nothing works.
Of course the original 500GB HDD spinner boot drive on my P70 has long ago been replaced with two 512GB Samsung 950 Pro NVMe drives in the M.2 bay (with NVMe0 set as the boot drive in the BIOS STARTUP list), and a 512GB 850 Pro SSD in the primary 2.5" bay.  950 Pro NVMe1 and 850 Pro SSD are both for "data".
Now the last time I did a BIOS update from the original 1.11 which arrived in the machine to 1.15, I had the same hang at boot time.  And ENTER didn't work.  But F12 did work, and I was finally able to get into the "choose boot drive" dialog of the BIOS and specify NVMe0, and it took off and I was back operating again.  I then re-entered the BIOS to specify that NVMe0 was the boot drive, and from that point on everything worked properly and normally again.  Didn't need to use ENTER or F12, it just booted properly again from NVMe0.
Well, this doesn't work now that I've updated from 1.15 to 1.21.  BIOS does not boot (it's probably reset the STARTUP boot order to default,... Read more

Hello everyone, I have a problem with Lenovo Thinkpad W520 (4270CTO). My laptop has a maximum screen resolution of 1920x1080.  When I first installed Windows 8 Pro (64bit) (UEFI installation) the boot logo screen during the very first run was in 1920x1080 for a couple of seconds later though it changed in very low resolution.I can't tell how much,but it is very low.Almost the same thing happened when I instaled Ubuntu and I started using the GRUB-EFI loader instead of the Windows 8 bootloader.The resolution on GRUB-EFI is very low.I tried to change the settings in /etc/default/grub file and after that I ran sudo update-grub, but nothing happened. Another problem is that although my installation is a UEFI installation there is no option to access the BIOS from Windows 8.I am referring to the option which appears when you go to "Change PC Settings" -> "General" on the section which says: "Advanced Startup" below that title it has a button which says "Restart now". Press that and a blue screen will show.The press the "Advanced setup" option and you will be transferred in another submenu.In this submenu there should be an 6 options and one of the should be about accessing the BIOS. Please mind that I have the latest BIOS version which I think is the 1.42. Any help is appreciated. Here are few screenshots. I hope they are helpful.(Sorry for the bad image quality)

Answer:Problems on Windows 8 boot logo & Grub-EFI boot loader & BIOS ACCESS

Although W520 has UEFI capability, it is UEFI spec version 2.0
Windows 8 requires UEFI 2.3.1, for advanced UEFI features like rebooting into firmware/BIOS setup.  There is no possibility to retrofit UEFI 2.3.1 onto W520.  Keep in mind that W520 is 2011 system and Windows 8 came later.
I have no idea about boot loader resolution problem.

It has happened to me twice...I accidentally deleted a partition and later found out that my system is dead....The only way I recover out of that is I reinstall Windows and then install grub again to recover the Linux partition. But I feel the delete partition is a very rapid process just taking seconds and in that I don't think files would be deleted, so I feel potentially I can recover the deleted partitions including the boot partition. But I don't know how to do it. Also now when the boot partition is deleted and the system is not booting up what should be done to recover the system and data?
Thanks in advance,

I'm wondering if this is at all possible on an external HARD DRIVE, not FLASH STICK.

I'd like to be able to take a large external hard drive, and partition the first 20% to use for boot images with some kind of boot loader, and the rest for data partitions.

Otherwise, can someone help me find an article to show how to get the following onto a usb flash drive along with a boot loader (and how big of a flash drive do i need?)

#1 Hi, basically this probem arose from nowhere. I came back from holiday 6 days ago and my pc took longer than i remember to boot. Only till i realised the next day and day after it was getting longer and some times not loading past the 'Windows' screen. Each time when it hasn't loaded fully, I turn it off and re-boot pressing F8 to get up safe mode, which doesn't work at all.
It gets stuck on '/avgdiseh' doesn't load past and will stay like that till turned off. Start up repair does absolutely nothing, it asks to do System restore which then errors and reboots, if i press cancel it stays on the 'Scanning' screen for hours.. (8 hours today)

#2 I've now seemed to run into another problem trying to boot from my CD drive. First time I loaded everything correctly got to 'install windows' screen clicked start up repair which did nothing. Ever since that windows won't detect my CD drive even though it opens and did read CD's.(watched a film on it the other day)

I've looked online and other people have had the same problems and clearly i haven't found a solution yet. I've tried cleaning the inside of my case, double checking connections, changing boot options. From what i've read its either a failed HDD, failed RAM (, or failed CD drive in the case of my second dilemma)

I'm just curious as to whether anyone can pin point what the problem is. If its an easy fix or whether it is possibl... Read more

Answer:Z510 'Default Boot Device Missing or Boot Failed' after BIOS update

You should probably reset your BIOS since I believe it is messed up now. Take out the battery.Press the power button for a minute. (just to make sure it is reset, usually 20-30 seconds work)Connect the battery and boot.

Two months ago I had trouble booting into Windows XP.  After much troubleshooting I decided it was time to simply start from scratch and reinstall the OS.  I purchased Windows 7 and installed it (along with a new motherboard to expand my options with peripherals).  Long story short, it worked fine for two months.  This two days ago I got the "Select proper Boot device..." message.  I have three hard drives in my computer (all SATA).  The primary drive is for software only... no personal files.  The second drive is my primary storage drive.  The third drive is a mirrored backup of the storage drive.  When I unplug the storage drives Windows boots right up without altering any BIOS settings.  The problem is persistent.  Each time I reboot it's the same thing.  If all three drives are plugged in, it won't boot to Windows.  If I unplug the other two drives, it boots just fine but I'm minus my data.  Any thoughts?

I have a IdeaPad Y560. We have had a strange problem for some time that I'm not sure how to solve. The laptop works fine once you've booted into windows but for some reason pressing F2 or F12 to either enter the boot or setup menu does not work. The screen simply goes black and stays that way. It is almost like I'm in the bios but can't see it on the screen. I have update the bios via the OS without a problem but the issue remains.  

Answer:Ideapad y560 will not boot to bios(Black Screen) but will boot to windows 10 and function normally

Same here...the problem started with me trying to update to windows 10.. Initially the update didnt work and i got reverted back to windows 7.. Later, however, i downloaded the win 10 ISO manualy and was succesful in updating to a Windows 10.. Within a couple of days however, all I got was a blank screen on booting to windows(the lenovo and BIOS worked currently until that time). So, I made a live win 10 DVD and reset my installation to a fresh install (kept my files). The installation aborted mid way.. Then, I had to reinstall freshly without keeping my files..Now, Win 10 works alrite but then while trying to go to my BIOS menu, nothing happens and I just get booted straight to the Windows environment..Can someone tell me what happened?

This morning I went to use my laptop and it is no longer booting.  The power will come on and the power button lights up, the keyboard lights up.  If I let it sit it will stop running after around 30 seconds to 1 minute.
If I click the power button after it started, I can hear the fans spin up then the system shut down.  I have ran the LCD test and it works.  Their is no boot screen at all or dell screen.
I updated the bios last week and I had run it since.  I also took the whole thing apart today to remove the bios battery for 1 minute and put it back together but it still does not run.
Is their a way to diagnose motherboard issues?  why would it not boot or is their more steps to look at?Thank you

Yesterday Windows Explorer began to stop responding fairly frequently, but would restart itself without issue and continue to run fine. Today, Windows now freezes completely every 45ish minutes - usually a random program stops responding followed by everything, the mouse gets stuck, CTRL+ALT+DELETE does nothing, and it stays frozen this way. I've had one BSOD happen right after this occurs (I couldn't get the error code with auto-reboot but I just turned that off). The most recent freeze I got a "The logon process was unable to display security and logon options when CTRL+ALT+DELETE was pressed" message, and Windows just stayed frozen that way with nothing responding.

Upon hitting Restart button on my case or following the BSOD auto-reboot, my OS drive (a Crucial M4) it isn't detected in the BIOS, leading to a "Disk Boot Failure" message. Oddly, if I do a cold boot from this point and power back on, the Crucial M4 is detected and Windows starts normally. I can also boot normally after shutting down and restarting from within Windows. But no matter what, around 45 minutes later Windows then freezes again in the exact same way, repeating the cycle. I'm totally at a loss, please help!

Dear Tech guy,

I sure hope you can assist me to get my sony vaio vgnfw44jb to boot into windows 7 again. Its been 3 days of wrestling and I got to the end of what I know.


My Sony Vaio started to run weirdly and do random things; I figured it was infected so here's what I did.

1. downloaded and ran the free malwarebytes tool. >> some things removed but system still buggy
2. system restore > chose a 'good restore point' >>> ran slowly > result system restore failed
]tried older restore points> system restore result> failed
3. Vaio stopped booting into win 7 >>> able to boot into safe mode>> inserted win 7 system build cd to reinstall but thats not allowed in safe mode
4. downloaded Kapersky rootkiller cd >> ran this overnight >> forgot to save log to usb drive >> vaio stopped booting at all
5. downloaded the Hiren CD ( yes, read its all pirated not asking for help with that) ran mbrfix tool >> no change
6. found techguy site, browsed around, joined, downloaded ubcd > burned to cd
7. tested vaio : power on > windows starts but does not complete > vaio care begins> not able to repair, suggests I repair registry
8. viao now has ubcd in cd drive, powered off

Any advice on how I can fix my pc and get it to boot or... reinstall win 7 without losing my latest data?

Is there a way to strip off the data and applications so I can restore to vaio after fix?
