[Boot Manager][SOLVED] Fixing UEFI Boot Issues: Black Screen After BIOS POST. Booting Only Possible From BIOS F12 Boot Menu

Question: [Boot Manager][SOLVED] Fixing UEFI Boot Issues: Black Screen After BIOS POST. Booting Only Possible From BIOS F12 Boot Menu

Hello,
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.
When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part of
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 believe I messed up with boot sector somehow... What needs to be fixed provided that Windows 8 will boot into VHDX file?
Thank you.

Well this is the world we live in And these are the hands we're given...

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.

Computer won't boot after bios upgrade.Quick history- computer was working but was dropped, damaging hdd- verified hdd damage by removing it and connecting it to another computer- verified computer hardware still good by booting and using it from ubuntu live cd- purchased SSD- changed Bios HDD support to Legacy mode so I could install w7- installed w7 64 bit professional- install went great, computer booted in windows, no lan or wifi yet : missing drivers- downloaded drivers and bios update from HP site for my exact machine to USB stick using different machine- installed audio driver- installed bios update, did not tamper with machine at all during BIOS update followed instructions exactly- after bios update  s/w said bios flash was 100% complete computer just hung for 15 min's- repowered machine: only get black screen- holding down F10 while powering up gets white "F10...BIOS Setup Options" text in lower left corner of screen, nothing else happens,I tried holding the windows and B key before powering then for a minute after powering several times, nothing happened. http://support.hp.com/us-en/document/c02693833I repeated that procedure half a dozen times with and without a USB with the BIOS update software on it in a USB slot, no difference.  Does my model support this key combination to load deffault BIOS settings? Do I have any other options to unbrick my machine? Any advice is appreciated.Mike

Belarc reports UEFI: American Megatrends Inc. P11-B2
Operating System: Windows 10 Home (x64) Version 1511 (build 10586.494)
Installed: 4/27/2016 5:58:22 AM Servicing Branch: Current Branch (CB)
Boot Mode: UEFI with successful Secure Boot.

This is my brother?s computer: originally it was Win8, upgraded to Win8.1 and then in Apr to Win10.
--- The computer runs OK and I?ve shown him how to use MRF to create system image backups.
--- Today Aug 8 we tried to test recovering yesterday?s Aug 7 system image backup.
--- It didn?t go well at all.
--- The MR recovery DVD-RW didn?t boot up in order to test it.

I thought of disabling Secure Boot to see if that was blocking the MR bootable Rescue DVD-RW.

However we weren?t able to boot into either the UEFI BIOS or Boot Menu.
--- According to our notes DEL is used to boot into the UEFI BIOS and F12 is for the Boot Menu.
--- However when booting up: in less than a split second something scrolls up but the computer immediately boots into Windows to log in.
--- That?s much too fast to get into the UEFI BIOS or Boot Menu.
--- Please help us figure out what to do.

Following that I?ll have to learn how to ensure proper system image backups and recovery using MRF.
--- I don?t recall any issues when I had Win7 but re-training myself makes sense to me because it?s obvious I don?t understand it well.
--- For now I?m going to completely uninstall MRF from his computer and hope to start over with a clean slate.

Answer:Cannot boot into UEFI BIOS or Boot Menu

Try F2 or F8 while Powering ON.. (which you might already Have). If no go update BIOS(which you might already have).

Assuming you have Windows 10 or Windows 8.1 on computer.. Do a Shift + Restart >> Troubleshoot >> Advanced Options >> Change UEFI firmware settings...Restart.
U should be be able to boot in BIOS.

Hi,
Sorry first time poster. I wasn't too sure whether to post to the Windows forums or hardware forums. From what I can see, this seems like a hardware issue of some sort.

The problem I have is that during bootup my PC goes through all the normal things. It detects my CPU, detects RAM etc. gives me nice BIOS Post messages that appear normal and then goes to a black screen. It will then sit there for 50 seconds (i've timed this twice) and then proceed to go to the windows XP startup screen (which takes about another 10-20 seconds to load up windows).

I've attempted to log the bootups by using the Windows Boot logger (by pressing F8 before windows boots). The ntbtlog.txt file isn't very descriptive, and only lists that a whole lot of drivers have been loaded, and some that haven't (it doesn't list any errors).

I've also tried using BootVis to analyse the bootup. I found this a little hard to decode the information it gave me, but there doesn't seem to be anything untoward happening.
The last boot logger I tried was bootLog XP (by greatis software). According to bootlog XP, windows is only taking 19 seconds to load up.

Can anyone suggest any other ways to analyse the boot sequence and discover where my computer is stalling?

(specs are below.)

Thanks in advance,

Matt

So i was playing Doom 3 and the game crashed so badly that i had to restart my computer (im running Vista 64bit by the way) and upon restarting it, it gets to the BIOS screen but after that it just goes black and nothing happens, i have tried the F8 thing but all that brings me to is this boot menu, but not advanced boot options, i have also tried pressing F8 or F5 after i selected hard disk from that boot menu, still nothing happens. So i cant access "restore to last good system configuration" because F8 doesnt take me to the right menu to do so. Also i dont have a vista install disk so am i SOL and have to just get another disk or upgrade to windows 7? or is there some other way to do this? Any help is appreciated!

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?

Answer:can't access UEFI BIOS and BOOT menu on my lenovo z580

I own a Lenovo G700, and I have heard that Shift + F2 will get you into the BIOS. It might work if all else fails. You can also call Lenovo support or search around a bit more. But in my case I have to use the hardware OneKey Recovery button to access it.

hi sivasandeep99,
 
Welcome to Lenovo Community Forums!
 
If you have tried FN+F2 when boot?
Or holding down Shift and clicking restart?
If those steps did not work either,  You might need to contact Lenovo Technical Support and have the system shipped to Repair Facility for BIOS Reflash.
 
Found this article but it is for the same model that has same issue like yours.

I just flashed a UEFI BIOS and did a clean install. I'm getting the error 0xc000000e only on reboot. If i shut down and turn on again it boots windows no problem. Please help!

Answer:Windows 7 and UEFI BIOS Boot Manager error 0xc000000e

What are the exact UEFI, CSM and Legacy BIOS settings in BIOS setup? Did you do a UEFI install, booting from a UEFI device to install, or did you install to Legacy MBR disk?

Unplug all peripherals and try again.

If you can get into Safe Mode, establish a Clean Boot from Troubleshooting steps in picture below. Then test your hard drive, RAM and work through the other steps to go over your install and hardware.

I dual boot to 2 different windows 7 installs. I have my primary for day to day stuff and the second install is for my DAW. I don't want to update the DAW to 10 because of the issues it may cause. I do want to update my primary install to 10. Can this be done or will I run into issues since the DAW install is BIOS?

Recently I played around with dual booting Linux Mint on my system. I decided that I would delete it for the present as I have other things to focus on. However, after deleting partitions and fixing my MBR to only boot windows my UEFI BIOS still has instances of Ubuntu as a boot option. Just for the sake of cleaning my system I was hoping someone could help with this.

My Motherboard is an ASUS M5A97 LE R2.0 with a UEFI BIOS. I'll provide screenshots of what's happening below. (Images were flipped upon upload for some reason)

As you can see there are two ubuntu options for some reason.
I tried to see if BCDedit would allow me to delete these but they didn't show up in BCDedit
I'm not sure where else to look to delete these options in my BIOS.

Thanks in advance for any help

After running MBR2GPT on my system with a successful completion, I realized that I don't know how to change the BIOS from legacy to UEFI, resulting in the inability to boot the GPT'ed system. I was running Windows 10 Creator on an MBR system using an MSI H61M-E23 (version 2) motherboard. I made the mistake of thinking that setting the boot mode to UEFI would be easy - I tried setting the first boot device to UEFI, but that did not work. The system does not boot - all I get is a blinking cursor. Any help would be appreciated.

I have a new Precision 7710 with a 2.5 inch 1GB SATA SSD (system boot=Disk0) and a 1GB NVMe PM951 SSD.
I have been attempting to install Windows Server 2012R2 on the second, M.2 SSD (Disk1) into a GPT, NTFS partition.
Since this system has no DVD, I made a bootable UEFI thumb drive with the contents of the .iso installation for Server 2012R2.
The thumb drive boots OK and I can begin installation, but when it comes to choosing the target for installation, the M.2 SSD is not visible in setup.
The M.2 drive is clearly visible inside Windows 10 Pro as the D: drive.
So...I mounted the .iso setup file in Windows 10 and ran setup.exe. The install began and could see the target M.2 drive, and began loading files on the second SSD. It then attempted the first of several restarts that come with this process with the new Server 2012 R2 environment.
It sucessfully modified the Windows Boot Manager before the restart, then restarted, and the setup program gave an error because it could not find the target partition on the second SSD.
The setup environment then modified the Boot Manager to "Windows Setup Rollback" and proceeded to enter an infinite loop, attempting to delete files from the unreachable M.2 drive. I manually choose Windows 10 on the boot menu, and once booted changed Windows 10 back to the default OS.
I've tried several things (turning off Secure boot, changing from UEFI to legacy bios--it won't boot at all that way) , but I can't get that second disk t... Read more

Hello all, I have been having this problem for awhile. It is getting frustrating. I my cd/dvd drive is not showing up in BIOS/boot menu or in device manager. Yet, I could still burn two DVD's and when I put a DVD in the light flashes and I can hear it working but nothing happens. Is there any solution to this? If so, please give me step by step instructions.

Answer:G585 - No DVD in boot menu/bios or device manager

Hi familytech,
 
Welcome to the Community Forums. 
 
The moment the device started not showing in the BIOS, is like saying that device is not mechanically available.
You can try to reseat the optical drive (page36) and secure it on its location or better yet have it tested in another machine.
 
Testing a known good DVD on the same machine would confirm the need for a replacement drive.

Hi, carlosrrjr
 
In the BIOS, there should be a settiing for Secure Boot, and it is likely set to Enabled. If this is set to Disabled, and the Boot Order settings are set properly, then you should be able to boot from external devices like a DVD. Just make sure the Optical Drive appears before the Hard Drive in the boot menu. 
 
Hope it helps,
Adam

I'm a bit confused with the info given, but if you cant restore/repair Windows, then what you should do is backup your data to another PC using a USB Adapter, then run Recovery on the internal HDD in the P305.

You should also update the BIOS.

I used to have a W7 system in IDE, MBR and since I had to reinstall everything from sratch, I decided to set my drives to AHCI, UEFI/GPT. After install, I checked the BIOS settings and saw that in my Boot Options I had the "Windows Boot Manager" set as #1, my SSD set as #2 and DVD drive as #3.
 
When I change the boot priority and set my SSD as #1, my computer won't boot and asks for a bootable device although the system is install on my SSD. I don't have a multiboot system, there's only W7 present so why do I have a "Windows Boot Manager" in my BIOS? I thought it was only for multi boot systems so I don't get why it's showing up here.
 
When I go to msconfig, startup, there's only one system displayed (W7).
 
Since I'm new to AHCI/GPT, I don't know what's normal and what's not. If it's not normal, how come I got this Windows Boot Manager in my BIOS? Maybe the old MBR wasn't erased even though I ran a secure Erase on my SSD?

After installing Ubuntu 16.04 LTS  I was unable to reboot into the newly installed system nor access the one time boot menu from F12 or the BIOS from F2 keys after the DELL logo and bar completed itself and displayed F12 and F2 in the bottom corner of the screen.
I can access  the ePSA Pre-boot System Assessment using CTRL Fn held down at boot.    I have run it twice, returning no faults.   Tapping the F8 key at boot has no effect.

Answer:Windows Boot Manager in BIOS boots only at Boot position 1

I hope I haven't misunderstood your question.
All motherboards have a boot priority list.
It will check all sources according to that list until it reaches a source that has a functional operating system or atleast a trace of an operating system boot file.

PXE boot is a network boot, so it will search your network for a server that contains an operating system and will boot that.
Windows should be installed into your hard drive and should usually be your first priority boot device.

However, since you have asked how to change this, simply go to the motherboard BIOS.
The keys vary from manufacturer to manufacturer, but a quick google search should help you. Common ones include F10, Del, Fn+F2.

Before the system has a chance to to boot, press the appropriate buttons repeatedly until you get access to the BIOS. Here you can navigate using your arrow keys on th keyboard to something a tab called something like along the lines of 'boot'.

Then navigate down and find boot order. The onscreen instruction will tell you which controls to use to change the order and move items up and down. Once you are satisfied, you may exit with saving changes and after reboot, the order you specified will be followed.

Cheers!

Hi,
My system does not boot, the BIOS is hanging at Loading of bootloader stage.
once i remove my newly replaced SATA hdd the system boots fine and does not hang anymore. after removing the HDD i can also boot via Bootable CD.but the PC does not start if HDD is plugged in.

My system specs:
AMD Athlon 64 3000+
MS K8MM-V -- details
1GB Drr 400Mhz Ram
Nvidia Geforce 6200
80 GB sata hard drive ST380815AS
Problem
My HDD crashed, so i replaced it with new one. installed it correctly. it booted fine. loaded windows on it in morning. now since evening. it does not boot.
I have checked the SATA-I compability jumper, its set at factory default i.e 1.5GB/s
also, the VIA Raid config which shows up just after POST screen, as trouble detecting HDD, sometimes it detects it and some sometimes it hangs.
but it sureshot hangs while loading bootloader stage

Please help

[edit]
I downloaded Seagate Seatools and tried booting with it. it does not boot with hdd attached.it hung at InitDisk function
so i removed the HDD and seatools booted fine. after that i again install the HDD *without* poweriting off my PC.
and guess what it worked!!
and i tested the drive with Short and long test. and it passed both the test without any troubles
 

Answer:System does not boot,BIOS hangs mid way after POST screen

Unless your controller supports hot swapping, I would NOT do that again.
Have you replaced the sata cable and or tried another sata pw connector?

FWIW just because a disk passes the drive maker's diagnostic, does not mean it is OK. I had a system a few weeks ago that passed ALL tests twice and I zero filled the drive; still problems. Installed a known good seagate drive, all problems stopped.

Thanks for Posting!
 
Upgrading the BIOS might set off something.
 
Check under Exit TAB and see if you have OS optimized or OS optimal Settings.
      Change it to other OS or Disable.
      Save and Exit
Boot into BIOS again.
      Check Boot Tab if you have now a Boot mode and Boot Priority.
       Set those to Legacy / Legacy first.
 
Look for Secureboot and disable it.
      Save and Exit and try the F12 and see if you can have the ODD drive as an option again.

Hi
After a failed windows update, I am not able to boot my laptop.
Finally, after being passed from one agent to another during some hours today, I was eventually forwarded to a 14th person at Dell, who was the right kind person to help me with my problem. Hurah!
But we could not find a solution.
During the call, I had to delete the Windows Boot Manager that figured in the sequence, and which was not working. And then to add it again.
So far so good.
I added WINDOWS BOOT MANAGER after clicking on $boot (after choosing one of my partitions).
But it then showed up as WINDOWS BOOT MANAG
I tried again Windows Boot Manager
which, again, came up as Windows Boot Manag
Two letters missing... So this is not working, and computer still doesn't boot into OS.
Any idea how to add Windows Boot Manager correctly?
by the way, I found this file bootsector.bak - is this of any use to restore my boot sector??
Would be great to get some help. I am on that issue full time since 3 days now, and can't even do my normal job.

Since I was having some issues with my system, I just reinstalled W7 from scratched on my SSD. With this new install I decided to go the AHCI, UEFI, GPT route instead of MBR and IDE like on my previous install.

Everything installed smoothly. I took a look at my BIOS setting and I can see in my Boot options that my #1 boot option is set to "Windows Boot Manager". My SSD is #2 and my DVD drive is #3. I only have one system installed (W7) so I'm not dual booting.

When I change the boot order and set my SSD as #1, my computer won't boot and tells to select a drive with a bootable system. "Reboot and select proper boot device or Insert Boot Media in selected boot device and press any key"

Is this normal behavior?? If not, how do I fix this?
Thanks

Answer:Why do I have to select the Windows Boot Manager in the BIOS to boot?

When you reinstalled Windows you should have disconnected the other drives and leave only your SSD connected as now you have your boot files on the other hard drive so either reinstall Windows disconnecting the other hard drives and reconnect when you're done or follow the suggestions in this thread

Answer:win xp hangs at BIOS boot menu screen

This sounds like it could be two things, dodgy memory or the PC is overheatingFor the first, if you can get a copy of memtest and let it 'do it's thing'. If it finds any problems you could try cleaning the memory contacts (carefully, Ram is VERY delicate if you dont know how dont try it) or replacing itThe second thing that could be causing this is that the computer is overheating and is shutting down to prevent damage.If it is this, then just open up the side of your computer and clean out the dust. You must make sure that heatinks and fans (such as areas like CPU, Northbridge, Graphics) are all free of dust to help flow of airHope this advice helps!

However, after backing up and reinstalling the OS, I found that when I tried to disable "Launch CSM" in my BIOS, all of my boot options would disappear and my laptop would continually boot into my BIOS.

Answer:Won't Boot, Black Screen, Can't get to BIOS

It could be a bad video card that failed by coincidence. When you tap F12 at boot do you get a Diagnostic menu? You can try powercycling the computer. Unplug the power cord, take out the battery, and then hold the power button down for 30 seconds. But the battery back in, attach the power cord and boot the computer. You may have to reset BIOS to default if it works.

I don't know if this is the right place, but I think so and I'll try.Well, I won't introduce myself, as I want to be quick.
Let's go to the problem. So I was using Windows 7 when I came out with the idea of installing Windows XP, as 7 was sucking my memory up (300 MB of my beloved 512 RAM). So I read a tut on how to install XP after 7 was installed, and after XP's first stage of setup, it told me to restart. But for my surprise it wouldn't boot (a screen appeared telling me BootMGR was corrupt). So I managed to get a Vista DVD (Not 7 cause I couldn't find it), and ran the Command Prompt. So I wrote what the tutorial told me to write:
-Bootrec.exe /fixMGR
-Bootrec.exe /fixBoot
It showed me up as the operation was successful, so I restarted my PC. Now, WTF, I can't get to 7 because a black screen (it was blank) stayed after 2nd Boot stage.
So I put the Vista DVD again on my drive and installed it over the partition where XP would have been. After installing everything I'd expect a Vista or 7 boot, but, again it wouldn't let me!
Now I got my PC ruined up, I cannot boot 7 from hard drive because of this. What shall I do? Is there a way I can get 7 back? Please help!!

I searched around the forums for a bit and even tried some things that could possible alleviate my problem, but to no avail. Here's the situation:

My main pc was having problems...I would be playing a game, writing an email or something as simple as browsing the web and my pc would lag for 5-10 min or would just freeze up. I would try to reboot the pc and sometimes it would get to the windows loading screen and it would freeze or it would just get past the loading screen and just remain black (I could always get into BIOS though). One thing that would always work would be for me to shut the pc off for an hour and then reboot. Then it would run great for a while.

I decided to just reinstall Windows 7 Ultimate and start over fresh. After installing the OS, I started to reinstall old programs and low and behold my pc would freeze/lag again. Rebooting would result in the black screen/freeze also. So, what I did was take everything apart and put everything back together again. The only thing I changed out was the cpu cooler, because I figured it might be an overheating issue (the gpu was never hot). So, after installing everything back the way they were, I powered up and the real headache started.

Answer:BIOS boot issue and has UEFI boot option one time, next time it doesnt

This all stems from having both drives connected at the same time when you originally set this up and has caused the MBR location for both drives to be stored on one drive, your HDD (spinner). Which explains your very first boot error message (No boot sector found please enter a disk or reboot - something like that).

I would start from scratch; remove the SSD first and leave the HDD (spinner) and do a clean install on that with your original OS. Then upgrade to 10. Once done remove HDD and attach SSD and do a clean install of of original OS and then upgrade to 10 on that. This way the MBR is stored on the correct drive for each OS install and this should correct your BIOS flash screen problem.

Background Info: The computer I am using I got from a relative who died. He had bought a HP computer with a Windows 7 Home Premium upgrade disc that he ran in order to upgrade from Vista to Windows 7. When we got the computer it still had all of his files and user account named Dave.

When I started using it, I left his files on there but deleted a lot of unnecessary programs I didn't want or need. I also renamed the user account from Dave to my name.....


Fast forward to the present. I got help from HP customer support last night to get a wireless printer we had boughten up and running and he said he cleaned up the registry to get rid of old printer files that were causing a fatal error loop during a printer install. It worked and I was able to successfully install the new printer.

Previously it said Windows Vista (Recovered) and also Windows 7 Home Premium (Recovered) both options would load Windows 7 though no matter which you choose.

Hi, everyone. I recently had a new computer built for me (http://pcpartpicker.com/p/svHXMp) but I've had an issue with actually getting it to load past BIOS over the past two weeks.

Currently, the system will boot to BIOS, as I don't have an operating system installed on my SSD, and then go to a black screen with a blinking cursor if I don't input any commands to take me to the status/options screens.

Yesterday, I tried installing Ubuntu on the computer just to see if I could get a working OS on it, but it went to the same black screen instead of loading the installer. I've looked in the options and the computer recognizes my HDD, SSD, and USB, and I've swapped the boot order around more times than I care to remember, but I honestly have no clue what's going on. Any help would be greatly appreciated!

The intent is to cause a keyboard error to force access to the BIOS. It may work.

PLEASE HELP! Window 64 was asking for registration before allowing access to windows. I tried to boot priority (with F2 and F10) windows 32 pro edition. I disabled every boot option except for boot from CD/DVD so it would read the installation disc first. Now it won't even let me into bios. It just says after eMachines pops up and then disappears the screen quickly says contact
http://support.intel.com/support/motherbaords/desktop, which was a complete waste of time. Please help me, at least, get back to the bios! .Any feedback is greatly appreciated! THANK YOU!

Answer:[SOLVED] Help me get a bios or boot menu back!

You didnt need to DISABLE every boot option, just needed to put cd/dvd first boot.

Have you tried calling on the phone to talk to a tech?

If your not getting the first screen to enter bios, then this could mean bios is damaged,

you will need to send motherboard to emachines.

I took out my 1TB 5400RPM Harddrive that came with the Ideapad Z585 and replaced it with a faster 500GB 7200RPM Harddrive.  I then changed the boot sequence in the Bios to start from the CD/DVD drive and installed windows 8 from Windows disks. I also installed the necessary drivers.  I made the new drive have only two partitions and no recovery partition. After installing windows the laptop was working great until I pressed F2 and went back into the Bios.  While in the Bios I changed the boot sequence back the way it was to boot from Harddrive first.  I also removed my password. Now everytime I try to save and exit the Bios the screen goes black, then goes right back into the bios. I removed the 500GB Harddrive and went back to the original 1TB harddrive that came with it.  Now the Bios works fine.  How do I make it so the bios works with the new drive? Thanks for the help Greg

Answer:Ideapad Z585 stuck in Bios boot menu - Can't exit the Bios

When windows 8 was installed was it in uefi mode and the disk formatted as a gpt disk? I'm referring to the 500 Gb 7200 rpm hdd. Aditional question: Is the Windows 8 that you use 64-bit?

I've been experiencing a completely black screen after my BIOS loads. A Windows update hit my computer last night and since then, the OS completely fails to boot.

Both hard drives (system volume and storage) are present and accounted for in the BIOS.

I tried Startup Repair by booting with my Windows disc, but it detected no problems and told me that my OS boots perfectly. Also tried some method I found on a forum saying Startup Repair must be run three times, but I got the same result each time.

Next step was System Restore. I have tried restoring from several different restore points, but I get an error message each time. Something vague, along the lines of "System Restore has failed." This is pretty worrying.

I tried to "upgrade" my Windows installation from the disc, but the next screen said to restart, then boot into the OS, then "restart the upgrade." No use to me since I can't boot my OS at all.

Anything to do with Safe Mode isn't an option either, since there is absolutely nothing happening after my BIOS loads up. Just a completely black screen. No Windows logo. No blinking cursor. Nothing.

All I can think of now is backing up my personal files and reformatting/reinstalling Windows from scratch, but I really, really do not want to do that. Any help would be much appreciated!

I'm struggling to work this out - (Windows 7 32-bit on a HP pavilion dv2500) I rebooted about a month ago (a few days after upgrading from vista to 7, but maybe this is unrelated?), and there was just a black screen, no cursor blink, no bios, nothing, but the disc light is flashing, then Windows startup sound goes off, so it has booted after all. I tried attaching an old VGA monitor and sure enough there's my desktop. I close the lid in frustration and unplug the external monitor. When I open the lid again the display comes on this time but its in 1024x768 (not 1280x800), and when I try to readjust the resolution its just not available as an option - loads of other resolutions, but not 1280x800.

So, I install the latest nvidia driver, flash the bios with the latest version, restart, but still the same. Randomly once when I F10 into the boot menu (which is appearing on the external VGA), then do a save and restart from there, the laptop display came on again, boots into Windows fine, at the correct resolution. I use this for a month or so, it sleeps and resumes no problem (I didn't restart it), everything working as it should.

Then the latest windows update comes along and requires a reboot, and I'm back at the same point - if I don't connect the VGA external then I've got a blank screen (no backlight, nothing), even though windows has started. But if I connect the VGA, put it into sleep, disconnect the VGA, resume from sleep then I've at ... Read more

My laptop is a Acer aspire 5738z running windows 7 home premium 64 bit and my problem is my laptop will not start. When I turn my laptop on it starts to run like normal: GPU fan starts, Disk drive kicks in, and the LED for the on button is working but nothing on the screen. I've tried too do alt + f10 for a restore, nothing happened. I've also tried to plug it into a monitor and my tv. Before this occurred it had been turned off during boot (don't ask why, I cannot answer that) and I preceded to take it apart(to fix the overheating issue due to acer not putting fan holes on the bottom of the laptop ((thanks Acer -.-)) and I didn't realise something was wrong with it until I reassembled it and tried to turn it on. So I'm not sure whether is corrupt BIOS, a hardware problem, or corrupt MBR (my own personal diagnosis, don't know whether it's right or not). Also I have tried turning the laptop off taking the battery out letting the motherboard discharge then pressing the power button for a minute, leaving it for a minute, putting the charger in then turning it on.

Thanks. =]

Answer:Laptop wont boot Black screen no BIOS

You may need to take it apart again and make sure everything is connected properly. Did you follow steps to keep yourself grounded while working inside the system?
As you add and remove hardware, follow these steps for ESD safety:Shut down and turn off your computer.
Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
Once these steps have been followed, it is safe to remove and replace components within your computer.

I hope someone can help. I have a DELL XPS 2710 AIO PC. It is now 3 years old (unfortunately the warranty expired 2 months ago). It now doesn't boot at all into Windows. I get a blank screen. This started suddenly on a restart.
I've tried many things. Removing the HDD and RAM. If I take the RAM out I get the double Beep RAM not found sound, so I know it detects that. I've taken the Motherboard batter out to try and reset the CMOS including switching the jumper. I've swapped the RAM around, plus tried with different HDDs. The Screen still works fine as when powered up with HDMI in it shows other sources, but the HDMI out doesn't display anything on other screens.
For the life of me I can't get the BIOS to even display so I can't check the settings or reset it!
I think things are loading in the background but I see nothing. If anyone has a similar machine can you tell me the button presses to reset the bios as I'll try them blind to see if it works>

so i followed this tutorial:
How to Run a Portable Version of Windows from a USB Drive

and got windows 8 on my drive ok. Issue is im having really problems getting the option to boot from the drive to come up in boot options. Basically only the notebook hard drive and PXE are an option UNLESS i go into BIOS and mess about with changing boot settings to and from legacy to UEFI (with / without CSM) eventually on turning on and off it will give me the option to boot to my drive but its really hit and miss. when i get the option all boots into win8 no problem.

any ideas to get this to work better? i dont really know the settings im changing and i know messing about too much in BIOs is bad!

my external drive has 2 partitions, 1 for win8 and 1 for my other files both are NTFS. the laptop came with an internal mSATA which is all formatted to NTFS even system reserved. I tried creating a partition of FAT32 for boot and that hasn't helped. same behaviour.

Hello, I was wondering if anyone had some experience with boot/startup issues. My computer tells me that it cannot detect an os. I have installed multiple Operating systems including linux based. The computer does start up sometimes, about 1/15 restarts.

I have tried resetting the phoenix bios. I have replaced the cmos battery, the initial tests specified a bad hard drive. Mem test was fine. It was a 200 GB (4200 rpm) I replaced it with a 500gb 7200rpm. After I replaced the hdd and installed the factory OS then began this new issue of no OS found. It HAS booted on multiple occasions. More so when I installed ubuntu. I have partitioned and set multiple OS including its factory Vista, ubuntu. I don’t even care if a different OS has to be installed or completely changing anything. Don’t mind learning Linux, that would be great actually. I just want this machine to run on startup. Any Ideas, tricks or new OS/software is accepted.

Is there some special trick to partitioning so that the bios reads the OS? Is there any possible way to reset or bypass the factory OS, or 'unlock' the computer? Maybe crack/replace the bios and set it up with a different OS. The factory disks dont seem to be doing the trick.




here she is, the exact model:

Hi everyone. Please help out here. I have an HP Pavilion G6-1d40ca. It crashed the other day while I was using it, and when I restarted it, it went to BIOS update. It froze while updating, and died in itself (I think the battery died, it wasn't plugged in. I never knew about BIOS update, so I wasn't expecting for the battery to die during the update, so I didn't plug it in.) Second time, booted it up (it was plugged in this time), and went into BIOS update once again. All's good, was able to use the laptop for about five minutes, then it crashed once again. Now, when I boot it up, nothing comes up on the screen. No nothing. The power button is on, the wi-fi is on, the LED light is blinking non-stop, more than 6 times than what is referred to the HP website.

I tried doing the remove battery and adapter, press power button for 30 seconds, plug it in without the battery, but to no avail. I also did the whole win+B, but doesn't work either. I tried pressing f11, but nothing comes up on the screen. I don't remember where I put the recovery discs that came with the laptop. I thought I put it on the box together with recovery discs for our other computers at home, but I guess I didn't.

Answer:Failed BIOS update,HP pavilionG6 won't boot up and only black screen

Did you run a BIOS update, because it wouldn't restart into one. What exactly did the screen say that made you think it was a BIOS update being done without running it yourself (unheard of).

What LED light is blinking nonstop?

Can you boot into HP Factory Recovery: HP Recover Windows 7 Operating System Using HP Recovery - HP Customer Care (United States - English)

You can try these steps for Troubleshooting Windows 7 Failure to Boot which will tell you if you can boot a disk to do repairs. If so besides links to the Win7 installer to use for repairs, there are also links to HD and RAM bootable CD tests to check your hardware.

But if this cannot get traction quickly what I would do with such a new rig is call HP Tech Support and have them walk you through steps to determine if it should be returned or if there is a known issue.

Hi all! I got a new W510 and decided to update the BIOS via the Windows 7 executable supplied by Lenovo from their Support-web.

The machine started to fire up it's fans after a while and the machine felt quite warm on it's top right side. I waited a bit (say 4-5 minutes) if there was some extra BIOS update that was being done but nothing happened so after a while I decided to shut it down. Now when I start it up, the screen is all black. Will this be covered in the included warranty? It has to be, right?

Hallo,

After creating a UEFI bootable USB thumb drive with Rufus (using Windows 8.1 Enterprise ISO x64), for a Dell Optiplex 3010 (configured as UEFI only, no CSM, latest firmware version, Windows 8 installed), I didn't see a USB boot option, so I tried to add one manually. Unfortunately I erased the existing boot option (boot manager) by mistake. Although there were two boot options for PXE booting, the machine will not start anymore, even when there is an active WDS server on the network.

I also see Led's 2 and 3 lighting up, meaning according to the manual 'hardware ok but bios possibly damaged/corrupt'.

I understand I cannot start the machine from a bios boot disk because of GPT partitioning, and the UEFI USB boot disk I made might be corrupt (as it didn't show up as a boot option), however I don't understand why it won't boot from the PXE network card, as these boot options are still there.

Any suggestions on how to solve this?

Thanks for any useful tips,
Bavo

Answer:Deleted Uefi boot option (Windows Boot Manager) by mistake

The Windows Boot Manager is held in the Bios and restores itself if you boot to a UEFI capable device. Could you please explain exactly what you did to "Add" the USB boot option?

I haven't used Rufus since it is so easy to just format the drive yourself, but it did format in Fat32?

I have the PXE boot options disabled in my bios since I do not have a network boot option.

Hey guys,

I've been searching the web for solutions for hours now and won't find anything that works for me. You are kinda like my last hope.

Situation
I have a Asus A54C Laptop here (it's my brother's), that won't boot. If I turn it on, it quickly shows the Logo screen and nothing else happens.
If I have a WIN7-DVD in the DVD-drive (created with downloaded ISO, it seems to be working on another laptop), the drive makes some noises but nothing else happens.
If I have a Ubuntu-Live-USB plugged in (worked on this Laptop before), nothing happens.
If I press F2 repeatedly after turning the Laotop on (it's the BIOS-key), nothing happens.

What I've tried
I tried several potential BIOS-keys, although I am 99% sure that F2 is the one.
I tried the turn off, deplug battery and cable, hit power-switch 20 times and for a minute thing.
I tried unplugging the Laptop while it was in the logo screen, hoping this would bring me to BIOS after starting it again.

How I got there
An Ubuntu system has been installed on the Laptop for a while. Now, my brother needed a windows and I wanted to create a dual boot system (what I had succesfully done before).
Some stupid mistakes later, I had a corrupted Win7 and wanted to overwrite it with a fresh install.
I tried to delete the 100MB system reserved partition (in the WIN7-installation menu) because I thought, a fresh install would create a new one. This took about 1 hour (for the 100 MBs) without any visible progress, I finally ... Read more

Answer:Laptop won't boot (Logo screen),can't boot from USB/DVD or access BIOS

Hello and welcome Joe mate the BIOS key is F2 and this is the manual for that model sorry but I can only access the English version - if you type in what you want to search for it automatically will go to that setting or instruction. https://www.manualowl.com/m/Asus/A54...261331?page=84

Now if you select the optical as the first boot device and it will not go then maybe it needs a new optical drive - very cheap these days and you may be lucky that it is held in with one screw on the underside of the laptop without any pics it is hard to tell - it possibly could be in that manual.

Now for the BSOD's please use these if you want to get them analysed

Hi,  I have an HP Envy 23-d010ea, which doesn't boot - at all. It switches on when pushing the power button, and doesn't react to any input, then restarts after about 60 seconds or so. I've read many posts addressing this issue, and tried all the proposed solutions. In particular I've tried- different keyboards, it's own, and others connected through USB - all USB slots. (btw not one LED switches nor flashes on the keyboard!)- hard reset (15 seconds power button while having disconnected everything).- switching it on with Windows button+B pushed down, in order to restore a previous BIOS, in case it's corrupted. Everything has failed. Can I mention that Windows 10 was recently installed (upgrade) on this machine, and I was merely doing a restart, aiming at reinstalling Windows 7 on it from scratch.  Please Help!Appreciate all the input.Many Thanks!

I was working on a customer's laptop, a Compaq CQ60, that refused to boot into windows and System Recovery disabled all recovery options except for Command Prompt.

On a hunch, after pressing Escape during BIOS boot, I selected HDD Test. The test ran and failed with "Replace Hard Drive." OK.. the laptop sat there for a few minutes and never did anything else, so I tried to get out of that screen. Nothing responded, so I just held the Power button to turn the computer off.

When I pressed Power again to turn the computer back on, the Power and Wireless LEDs comes on, the CD drive is accessed and then the HDD LED lights up for a second and goes out. The screen never comes up nor do the backlights.

I have tried hooking up an external monitor, but that never shows anything either.

I have tried taking the memory out, cleaning the contacts, putting them back in, swapping the modules around, booting with one or the other.... No effect.

I pulled the battery and the CMOS battery, unplugged AC and let it sit for a good half hour. I held the Power button for thirty seconds. Plugged the CMOS battery back in then the AC. Turned it on and still no go.

I cannot figure out WHAT could have happened!? Any other ideas? Thanks...

I recently updated my BIOS using this package: http://support.hp.com/us-en/drivers/selfservice/swdetails/HP-Pavilion-dv6-Entertainment-Notebook-PC-... Now when I enter the BIOS, then Boot Options, it allows me to Enable/Disable Legacy Boot (which I assume means UEFI/older BIOS?). Since I am running Win 10 64-bit, I would prefer to use UEFI.  However, when I disable Legacy Boot, then reboot, it says boot device not found. Only reverting to Legacy Boot allows me to boot. How do I configure Windows 10 to boot with UEFI? My Older BIOS was F.0A, new one is F.2E.  This BIOS also fixes the battery indicator, so I would perfer to stay in it.

There are other ways, but you may not be able to boot properly and you need to make a repaor. So the first suggestion is preferable.

Hi, I recently fomatted my hard drive and reinstalled windows. In the process I got rid of the 'unecessary' partitions. One of them was the mbr partition. Yesterday I went to the bios and set it to uefi boot up. Of course now the computer does not boot up because the partition is missing. The boot Manager is has an empty list... I am not sure how to proceed Is there anyway for me to get out of this mess? Can I use an external hard drive to boot up the computer and change the bios settings or boot up from an externbal hard drive and reformat the disk but this time set a mbr partition. Please helpSeb

Dear Bleepers,
 
this is our strange situation:
My friend has a samsung laptop Ativ Book 2 (np270e4e) with windows 8.
After few problems when updating to 8.1 (it deleted the o.s and gived only a bsod saying that there is not any os installed), she decided to buy and install windows 7 so she disabled the uefi, setted the legacy mode and the boot priority first to the usb hdd (we have a bootable iso).
Parphaps every time we restat doesn't boot from the disk but showed the windows 8 bsod. Naturally the f4 for restore gives anoter bsod for not founding any partitions!
We discovered that it's not possible to boot from the disk, so we made a bootable usb driver with the official iso.
After that we picked up the hard disk and delete all partition from another pc and disabled all the boot driver but the usb hdd. After that it booted from the pen drive with official w7 iso.
The installation was completed in about 30 minutes. We started to install the drivers, chipset, intel storage but:
the next reboot it showed this message: all boot options are tried. press f4 key to recover with factory image using recovery or any other keys for next boot loop iteration and it was a continue loop and can't access the bios.
Strangely when the usb driver with the official w7 iso was inserted it said: "press any button for starting with usb driver"  and if we don't press anything windows started normally.
So we tried to install another time thinking it was a driver conflict but the second ti... Read more

Answer:All boot options are tried, no (uefi) Bios

Seems to be a common problem with Samsungs. See this thread and the post by François.  Can you access the boot menu by tapping F2 instead of holding it down? See if you can access the computer with Fatdog64. You will need to burn the iso file or use Rufus to create a bootable USB. If the USB does not boot then use GPT as a partition scheme in Rufus. 
 
According to here F2 is the boot menu for a Ativ Book 2, 8, 9 but F10 is the UEFI access key. Try tapping F10 at boot.

so the only way i could figure to boot from media at clean install was to boot from legacy mode.... is there an "easy" way to swap the boot from legacy to uefi? i'm only asking because it takes about 3 minutes to boot from legacy instead of 20 seconds and my ssd drive is missing??













Solved!

I just bought sony vaio S Series, with original Win 7 home basic 64 bit. But, many of my device such as printers, network wifi and etc not support for win 7 64 bit. Now, I want to install win 7 32-bit on my laptop. But, My CD Win 7 bootable won't boot at my laptop. After i check bios, i found something strange on boot menu orders, if the boot in "Legacy" mode, that laptop will boot from my cd. But if "UEFI" mode, looks like the system has ignore my boot cd, and go straight to windows 7 64 bit. Has anyone solve this problem? Will somebody help me to solve my problem? Thanks anyway

Answer:if UEFI mode on Bios, Cannot boot from CD... :(

You can install 32 bit to an EFI BIOS but it has to be in Legacy mode, with EFI Boot disk removed from the BIOS Boot order, and the HD wiped with Diskpart Clean Command so installer can reformat it from (EFI formatted) GPT disk to the normal MBR disk.

Follow these steps to get a perfect normal Clean Reinstall - Factory OEM Windows 7.

I don't have the option in windows to boot back into the UEFI setup. In my motherboard bios setup there is an option which allows for the selection of UEFI, Legacy and UEFI or Legacy, When I change this to UEFI my pc wont' boot and the error message is that no UEFI partition was found.

I think it may have been deleted when I installed Windows 8.1 initially because i had to convert from MBR to GPT. Or so i read on one of the forums.

Is it possible to restore my UEFI partition so that I can use windows to enter the bios setup. I've had the boot on ultra fast and it took me a week to get into the bios without using the delete key. I had to use Gigabyte utilities which include drivers that crash windows. So i want to remove them again ASAP.

Any help appreciated.

Answer:UEFI option instead of Bios boot

Well to get back into UEFI mode you will have to reinstall in UEFI mode there is no other way, Sounds like some how your OS got converted to MBR so It may not boot either MBR or UEFI but you can't convert back to UEFI you have to Reinstall. If you have data on that disk you need to recover you can pull the drive and hook it up USB to another computer and recover your Data.

Hello Everybody, So I had a massive brain fart when I was messing around with my T500 to get my discrete graphics card working again (it had been out of commission for some time spanning a changeof OS from Vista to 7 and several reformattings), and I changed my graphics device setting from integrated graphics to discrete graphics in the BIOS without actually having the working drivers for my discrete graphics card installed. Now upon boot, I'm stuck with a black screen. I can't access the BIOS, and I'm pretty sure my laptop's just hanging there with no components booting up.  I have already searched for solutions others have had in my situation, and none work/quite fit my situation. The closest situation someone else had to mine had a solution involving applying pressure directly to the GPU and hoping booting up will get somewhere where the BIOS can be accessed again. (http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T500-Hybrid-Graphics-Problem-How-to-blindly...) Worked for that person, but not for me. Does anyone have any solutions or suggestions on how to proceed? Thanks in advance! -Zeak

For this moment i tried:-reinstall windows- nothing happend-power on/off with/without battery-the same as above-detach this little battery to reset bios- nothing-change ram stickThe last thing I tried was update BIOS. Downloaded the latest version (3.09) of BIOS. In windows restarted and failture (invalid firmware image) . I know that i should disable Secure Boot- done (BIOS says that is disabled) and the same message. I tried download 6 times and all failture.
