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

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

Hello,

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!!

Preferred Solution: Dual Boot: Win7: Boot Manager Status: 0xc000000f boot selection failed

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 http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

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

Hello,
I have a Windows 7 Home Premium 64 bit.
Yesterday I accidentally 'killed' csrss.exe. Then, after a bluescreen, my computer restarted and I got the following message:

1.Insert your Windows installation disc and restart the computer.

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

So I tried that, but when I clicked "Repair your computer", I got another error message:

Well; one thing; did you remember to backup anything that you know you is important? Because If not you may be out of luck as it sound like some good sized corruption happened. Which leads me to think that the only way to fix this may be a complete clean install of windows.

Hi, I keep getting this message at startup which is strange as my computer was fine. I was using my computer all day today and then I turned it off and when I turned it back on later, I immediately got this message.

I don't have an windows installation disc or USB and I don't have a DVD-ROM. I tried some advice on other threads involving shift + F10 or pressing F8 by itself and nothing happened. I only have press delete for setup and F12.

I also noticed that a fan that was previously turning on and working fine before is no longer working. I'm not sure if this is related to what I'm currently experiencing or not.

Anyone got a 0x9f bugecheck on rebooting after updating from Build 9841 to Build 9860? No .dmp files written to system. After 3 or 4 hard resets, W10TP finally booted as normal.

Looks like Windows tried to boot from my USB-connected Garmin GPS??? This was the first time I had connected the Garmin using Build 9860. Previously it had been connected multiple times on Build 9841 without any trouble at all.

I followed the repair instructions using the Windows 7 installation disc. In the end it reported that "Startup Repair could not detect a problem" and nothing was repaired.

I have run CHKDSK on all listed drives and no errors were found and it did not solve the problem. I have checked the boot order and it is correct.

I have tried all the Bootrec.exe fixes.

I have been searching for a solution for hours, including on this site, and cannot find how to fix this. Any help would be appreciated.

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 selected the option, and a light blue/gray screen would appear, I'm assuming the background of the Recovery Partition screen. That was it. I could move the cursor but that was all. It was exactly the same, except the background color had changed.

Next I used the Recovery DVDs (AI Recovery Burner), [Esc] on bootup, select optical drive and press [Enter] to boot from Recovery DVD. Then [OK] to start to restore the image. Then [OK] to confirm system recovery.

Hey guys,

I've been looking at a PC for a friend and it's proving to be a bit of a nightmare. Here's the issue and a description of what I've tried to far.

0xc000000f the boot selection failed because a required device is inaccessible.

I tried a number of things first, such as ensuring every device unplugged bar keyboard and mouse etc. I then attempted to repair windows by putting a windows install on a bootable USB. After selecting the country, it would hang on the setup is starting screen and do nothing. I tried doing repair windows, and nothing would happen. From there, I installed it onto a disc instead (just incase) and got the same result.

After that failed I tried resetting the CMOS, flashing the BIOS etc and still the same error.

I'd basically come to the conclusion that the HDD is faulty and needs to be replaced. However, my concern is that as the setup isn't even loading from the disc when the HDD isn't involved then there could be a different issue.

I can't use the built in acer erecovery because it just hangs on please wait, I cant boot into safe mode, I can't access windows at all. I've tried almost every suggestion from a dozen different threads. Before I purchase a new HDD, I need to be certain that's the issue.

Sorry if that's a bit long winded, but any suggestions? I've tried quite a few things so will reply if I've already done any suggestions posted.

Thanks,

Hello and welcome aria mate try this Clean Reinstall - Factory OEM Windows 7

Read it thoroughly first and then make sure you pick the original version of Windows and don't do what some daft people do think they can put on Pro or Ultimate when the original version is Home.
See my pic for picking the right version I use a disk but a stick is ok for the ISO.

PS Meant to mention this will also get rid of all the Acer bloatware but do backup any dtat if you can.

Hello.

I previously had a Windows 7 installation on a 320gb hdd, but decided to reinstall on my 120gb ssd, leaving my previous install on the 320gb hdd in the meantime.

Install went OK, rebooted a few times after installing updates, etc. I decided to format the 320gb drive with the old install on it after copying some data from it onto the ssd with the new install. Format could not be done in Windows due to the option being greyed out, so I did so from the Windows 7 install CD. Rebooted, error appears from title.

"The boot selection failed because a required device is inaccessible. "

Booted from CD again

1. ran startup repair with no change

2. Executed bootrec.exe commands /fixboot and /fixmbr, reboot, no change

3. Verified boot order and ssd recognized as Bootable in bios.

4. bootrec.exe /scanos = shows 1 windows install present on "C:/windows"

5. bootrec.exe /rebuildbcd = installation detected. Pressed y to add = "element not found"

I'd rather not reinstall and update and juggle all that data around again if possible. Any help is very appreciated.

Update: reinstalled. Meh

Answer:0xc000000f "The boot selection failed because a required device is ina

Hiya and welcome to SevenForums!

From my knowledge of these kinda BSODs(I'm not so good at solving these kinda BSODs) is that the 320GB harddrive had the 100MB reserved system data on it and you formatted it so you made the computer un-bootable. I have no idea how to solve it but i think that is the case.

I am receiving this error, when I try and boot Windows 7.

I have run the Repair Startup option from the Installation DVD, and it performed a System Restore [only] the first time, but fails to resolve the error.

I believe this occurred, when I accidentally powered down the computer, while it was attempting to transition to/from Sleep/Standby Mode.

Reading other articles around the web (http://social.answers.microsoft.com/Forums/en-US/GettingReadyforWindows7/thread/5da88257-837d-4475-ad6e-9ea8968826f4)
I get the impression that the accepted solution is a clean install.

Is a Clean Install the only way to resolve this error?

I can provide detailed specs and error reports to assist in any bug-hunting.

Thanks.

Answer:0xc000000f -- The boot selection failed because a required device is inaccessible.

Go into your Bios and check to make sure that the right boot drive is selected. I've no idea why, but I've seen the boot drives get mixed in the bios setting on some systems resulting in the computer trying to boot from a non-bootable drive resulting in the error message you have received.

Hi guys I got a samsung np355v5c laptop for my son, I've got the same laptop also and was just setting it up for him when it restarted and came up with the following error. It is running windows 8.1 and didn't come with any disk. I was installing samsung recovery tool before it failed, and it came up with a box saying there was no recovery patition on the computer would i like to restart and try again. it was then that it came up with the following.

Answer:Win 8.1 failed to start, file \boot\bcd, Status 0xc000000f

Open the Command Prompt when the Installation DVD Loads and type the following commands.chkdsk /r c:
chkdsk /r d:
chkdsk /r e:
chkdsk /r f:.etc until you get the message that the volume could not be opened for direct access. For any drives that do not give the message:
"Windows has checked the file system and found no problems"
run chkdsk again as above. In other words, if it says:
"Windows has made corrections to the file system"
after running the disk check, run the disk check again.

I realize you may only have one disk show up in Windows explorer, but you may have more than one disk through recovery options. This is because the system creates a hidden boot partition (which will be C: in recovery), you may have a recovery partition for your PC that is hidden (which will be D: in recovery), and you will have your primary Windows partition (which may be E: in recovery). A custom PC will likely have at least C: and D: to scan.

Greetings, first of all I have to declare that I am not very tech savy so please bare with me. I am using win 7 home premium x64 intel core i7 2630qm on a Asus N53SN notebook. Ive had it for about 3 or 4 years with no problems whatsoever.

This tuesday though after Ive got some updates istalled I was having trouble booting my system. I was getting this message. After couple of failed windows startup repairs It was suggested to me by the system to restore my Windows operating system to a previous state which I did and it fixed the problem for the time being.

On wednesday I left my notebook on for the night and in the morning I noticed that the update which caused those problems the day before was probably installed again but this time I was left with this screen.

The thing is that my notebook came with an already preinstalled windows 7 home premium x64 and therefore I dont have the installation disc. One of the users on reddit suggested to me this method so I gave it a shot and followed the steps on the site. At the end of the process I was left with this which looked very promising to me (here is the link so you dont have to type it manualy Ubuntu Pastebin). Unfortunately after I rebooted my system I was left stuck on this screen since. (if I press ctrl+alt+del nothing happens)

I am not sure if it will but I have recovered tons of data etc using this method both on "dead" or just plain drives that you cannot get data from using Windows.

Also usually most machine have a factory restore partition and that just means booting and tapping the restore key but that will just reinstall Windows back to as it came out of the factory - no data or programs will be saved. What that key is I am not sure just Google for it although I have an idea it it F9 while booting.

So i had to back up the files and reinstall everything.  Before i reinstalled windows i scanned for malware with hiren's boot cd with all the antiviruses available on minixp mode.  It found a few viruses and removed them but it was to late... I sugjest that you scan for viruses with hiren's boot cd.  I hope your system is not to far gone.

If you've installed to SSD in UEFI mode then the Windows Boot Manager might need to be in first position in BIOS Boot Priority order.

Do you have a bootable OS on the HDD, or did you previously so that boot code might still be on it if it hasn't been wiped yet?

Hi everybody,

I am dualbooting Windows 7 Ultimate and Arch Linux (using rEFInd boot manager) on a GPT disk and (unfortuunately) have an UEFI system.

My setup used to work perfectly fine, until I recently updated rEFInd - and following this - deleted a paramount file on my ESP: bootx64.efi.

Obviously, I could not boot any OS anymore, so I tried to restore the bootloader but during this process I killed all my partitions.

Luckily, I could restore them using the tool Testdisk on an Archiso live usb stick. I restored bootx64.efi and wanted to boot Archlinux ... where I was greeted by an error message telling me that the root device rEFInd is looking for is not present. I could fix this by adjusting the PARTUUID in the respective config file and now I am booted to Archlinux. So as it seems, recovering the partitions using Testdisk resulted in changed UUIDs for my partitions.

However, I still can not boot Windows 7 because all I see is this boot error:

You are right that you have changed GUIDs for all your partitions. In this case, it is impossible to recover your Windows with the recovery tool.

Hi,
I booted up my computer today to find that whenever I try to select an option from the booting screen, the whole computer froze, as in, the timer counting down the auto choosing feature froze, I couldn't move anything. I thought at first it was the keyboard, as I use a razer product, I thought the drivers weren't loaded and it froze it. I tried it with the standard keyboard it came with and still froze at the screen (by the way, its option chosen is startup repair, im trying to get to start windows normally). I thought it was the monitor next and switch it around to no avail. I then dug around for a few hours to find my window repair disks. I get a prompt on screen to press a button to continue, which then freezes my PC. If I leave it at that screen for a while, startup repair is launched and I get a Status: 0xc000000e and the info says: The boot selection failed because a required device is inaccessible. Also, choosing any option with my motherboard BIOS also freezes/crashes the computer.
I really need help with this guys, thanks.

Hello, I have recently installed windows 7 on my 60 ocz harddrive and had a previous windows folder on my c drive disc drive. I wanted to get rid of all the old files and folders so I ran Dban to nuke the hard drive. Now I cannot access Windows at all.. Boot manager is missing and I cannot recover it by using the installation discs.. It gives me this error whenever I boot the install disc.

Windows failed to start. A recent hardware or software change might be the cause. To fix this problem.
1. insert your windows disc.
2. Choose your language
3. Click "Repair your computer"

File: \Boot\BCD

status: 0Xc000000f

Info: An error occurred while attempting to read the boot configuration.

I cannot access Windows repair

Things ive tried


1. Resetting Bios to default
2. disconnecting all hardrives but one to install or repair windows
3. using the installation disc to repair windows

I am about to give up and buy a whole new motherboard and harddrives because this has me truly stumped.. If anyone can help that would be great.

I tried to set up my desktop computer running Windows 7 Ultimate 32-bit to dual boot Windows XP Home. It didn't go as planned and now Windows 7 will not boot. I get the following error message:

"Windows could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and disk hardware. Please check the Windows documentation about hardware disk configuration and your hardware reference manuals for additional information."

I tried deleting the Windows XP partition and double check the boot order in the BIOS but no luck. I'm hoping someone here will be able to help me out. Thanks.

Answer:Failed setting up dual boot Win7/XP - cannot boot Win7

Set the Win7 HD first to boot in BIOS setup, after DVD Drive.

Boot the Win7 DVD or System Repair Disk, follow these steps to mark Win7 or it's 100mb System Reserved partition (preferred if you have it) Active: Partition - Mark as Active (Method Two)

Next boot into DVD Repair console or Repair CD, accept any offered repair. If none offered or Win7 doesn't start after reboot, access System Recovery Options to run Startup Repair 3 Separate Times
to rewrite the System boot files to Win7 partition or it's System REserved boot partition.

If it fails after 3 times attempting to rewrite to SysReserved partition, change the Active flag to Win7 partition and try repairs again.

Hi there,

I've updated to the latest bios on my new mobo ( Gigabyte z97x SOC Force ) and ive done a fresh install of windows several times on the SDD. I also ran crystal disk to check health on the SDD and it came back healthy.

It seems mostly my boot problems are linked to plugging in the two other HDDs, though I've no idea why this would be, and how to fix it? Is it a motherboard problem or a HDD problem?

Any help greatly appreciated.

Whenever I try and install win7(iso image) I get the boot manager window saying that a piece of hardware is failing or not connected properly. I've tried it with two hard drives and the intel ssd I bought for the build. What's annoying is that this error is sporadic, with my old seagate hd I was able to make it through the loading of the windows files and all the way to the language selection windows screen. So I cancelled it and decided to try again with my ssd. Since then I've gotten the same error.

Hi, I recently discovered this awesome forum, I'm wondering if someone can help me with this issue. I'm really desperate ...

My tablet's model is Linx 1010 (Intel Atom Z3735F 1.33Ghz, 2GB RAM) with Microsoft Windows 10 32 bits pre-installed on it. I have been using it for more than two years. But suddenly, last week I tried to boot the tablet as usual, and I faced with this error on it:

Windows Boot Manager boot failed.

Upon pressing OK a new message appears:

Upon pressing OK another message appears:

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

gramenauer,

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.

i recently rebuilt this into a new case and it had been working fine. Mainly using the win 7 os but more recently using the win 10 os more and more. The way it has been working is that win7 is the default boot and I have to hit the delete key on startup to select win10 to boot from.

today I was on win 10 but needed to reboot to 7. Upon doing so I hit this message:

It then gave me the option to boot to win10 as it is the next boot option on the list. Win 10 is now giving me the blue screen "memory management error" although I have been able to get into win10 after some more rebooting.

I ran SFC scanner and it told me that there were some problems that it cannot fix.

Everything is unplugged apart from mouse, keyboard hdmi to screen and ethernet cable. Unplugging the win10 drive from the mobo and switching the win7 drive to another port has not helped.

Has my ssd failed? has win 10 done an update that has caused this problem? It did update today, in fact the first error message I got was after win10 shut down, and when I booted into it again it installed some updates before launching.

Answer:dual boot win7/win10 wont boot to win7 anymore +BSOD "memory managemen

Hi @vinvanda.

As far as I can understand from your post that you had W7 and W10 as dual boot in two different disks.

From the uploaded data we could not find a hint of the BSOD that you said (it is not recorded anywhere, probably because it happened during boot); but some other statements are supported by the data.





Windows failed fast startup with error status 0xC00000D4.



Now, it is STATUS_NOT_SAME_DEVICE; reads as .... "The destination file of a rename request is located on a different device than the source of the rename request".

Now I am making a guess. It it is wrong, please rectify and state the proper situation.
You name the Windows 7 Disk as "system" and the Windows 10 disk as "Win 10". You also said that windows 7 is the default boot. So I am guessing that the boot files are in the the windows 7 disk.

The board is set as Legacy BIOS. So Fast Boot is not possible here; and if Fast Startup is enabled, windows7 needs to disk check in every startup. It is desirable to keep fast startup disabled on a computer with W7.

Now Coming to the "Secure Boot Violation". Windows 7 does not support it at all. And, it is the Firmware Validation Process of UEFI; whereas your system is set to Legacy. I think here lies the issue.





BIOS Mode Legacy

Several weeks ago I upped to windows 10 on a dual boot system running windows 7 and XP. Win7 and XP are on different partitions. Over the last week, the XP would not boot unless it was directed to the last successful configuration. I attempted system restore from XP with no success. Then I booted XP in safe mode and did a system recovery "successfully", sort of. Now XP will not boot in either normal mode or safe mode even after letting it sit all night, so I cannot undo the system restore.

I cloned and activated the hard disk before upgrading. I scanned for viruses before system restore.

I was wondering what the best option might be. I could copy the XP partition back from the clone and reactivate if it will let me or I could secure erase the hard drive with the win 10 up and XP and revert to the clone.

Just curious. Is fast boot enabled on the Win 10 install? As I understand things, this should not explain what you are experiencing. It could conceivably cause corruption of the Win 10 partition if XP is booted and the 10 partition is written to in its hibernated state. But it should not cause corruption of the XP partition. In any case, you might try turning it off anyway if enabled.

I have an msi wind, and it runs Xp, but i tried dual booting osx and everything goes fine. Though now i cannot access Win Xp cause it says im missing the hal.dll.

So there is something wrong with the boot.ini file.

What can i do?

Things i have tried
1) Modify the boot.ini from osx but the file is protected!
2) Use the recovery disk but i dont have a cd drive! and getting a usb is not an option.
3) Safe mod or command promt mode did not work
4) Tried installing Ubuntu onto an external hard disk so i can modify the partitions, and i got ubuntu on my ext hdd now but when i in bios tell the pc to boot from usb it just have that flashing cursor and nothing happens!.

Seriously, for two days i have googled everything and been to msi wind forums, but i cant find a solution.. Im not that kind of guy who does not try before he asks!

How can i make that Ext Hdd bootable?? Or can i some how get Recovery console to run from Usb flash drive??

I need my msi wind for school, so i really could use some help. Thanks in advance, if you need more info please tell.

Answer:[SOLVED] Cannot access Win Xp (dual boot failed) hal.dll missing, cannot boot from Ex

I don't think there is anything you can do unless you boot from an optical disc. That means getting an external optical drive. But google for how to make an ASUS EEE PC boot from a USB flash drive and see if that procedure will work for you with the Msi Wind also.

 I am now enjoying XP pro sp2 after partitioning my HD with Acronis Dir. Suite with Vista pre-installed when bought last October 07. XP works fine alright except for that one Lenovo care button.      I have learned to appreciate the classic way Lenovo has applied and developed with these two Systems. It's just a matter of getting familiar with how they ..."Defragmented" .... caring for your computers as congruent with the operating systems installed which actually makes things a lot easier to maintain your Windows than the usual way.   Anyway, I believe my issue here is how to make Lenovo systems recognize VistaBoot Pro  so i  can make a choice over a dual boot system.  As it is now,  N100 always go straight to the XP system partition when started,  and i cant get to my Vista anymore.  I'm still trying to look around lenovo in hopes of finding an easy resolution for my issue and hopefully there is one environment out there for dual boots.

Answer:N100 Dual boot attempt failed by Vista Boot Pro

 See control panel - system properties - advanced - startup/recovery -You should be able to see boot related options.(default OS, time, edit boot txt file).If you don't see Vista in OS options, then I think this is due to change in windows MBR..not sure. Microsoft provides a MBR repair tool.Otherwise just wait for some expert opinion here.

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.

Thanks ever so much in advance for any help you might be able to offer.

All the very best, May the 4th be with ...always...

I wanted to set up Ubuntu on my computer, and followed the instructions in the first answer to this thread: dual boot - How to install Ubuntu alongside Windows 7/8 - Ask Ubuntu

As instructed, I created a logical partition using EaseUS software. I did this on my H:/ drive, a hard disk drive (whereas Windows 7 was installed on C:, and SSD).

After a mandatory reboot for the new partition changes, I did not immediately go to install Ubuntu, although I had Live USB to do so. Instead, if I remember properly, I booted into Windows to make sure everything was OK, but only to find out that some "Windows could not boot properly", giving me the option to 'Launch Startup Repair' - which I did, but to no avail. All it did was reported that some 2 system files were missing or corrupt.

I then installed Ubuntu on a third drive because I still needed it to perform some benchmarking. I did this using the 'install alongside windows 7' option.
But now that I don't need Ubuntu anymore, all I am interested in is getting back to Windows, while keeping all the files and programs intact.

How should I go about fixing this? Delete the logical partition on the other drive? I also have that Windows installation CD, and I'm thinking its repair options could be useful - but not having a whole lot of self-confidence, I don't know what steps exactly to take to preserve my files.

Any help is greatly appreciated!

Hello everyone, I have a Dell Optiplex 760 SFF that has both win 7 and win 10 installed on a 1TB hard drive in the following partition order:
500 mb system reserve, 100gb win 7, 750gb data, 80gb win 10
I've also disabled the metro bootloader, as it wastes times when booting to win 7.

Whenever I reboot to Win 7 after booting into Win 10 before, the system requires a chkdsk of the Win 10 and data partition. I looked around the forums here and the win 10 forums, and have disabled fast boot in Win 10 as mentioned throughout, but it still results in chkdsk being required.

I've tried to do this on other computers such as an MSI laptops with Win7, with similar results.

Is there something else I need to do so that Win 7 doesn't do disk check?

Thanks for all the help in advance.

I have a dual-boot setup on a Dell XPS 8900 that I've had since Feb/March. The dual boot setup has been working fine, with zero issues since then, then this week I just booted into Win7 a couple days ago and it ran chkdsk automatically, erased some files, restarted, and booted into Win7 fine. I used my OS with no issues and shutdown. But this morning I tried to boot into Win7 and my system can't find the operating system.

I bought the computer from Dell with Win10 installed on their standard 1TB HDD and added a WDC 2TB HDD and installed Win7 in Legacy. I can still boot into Win10 with no problem in UEFI, and while using the OS I can see my other Win7 HDD, all the files are still there and I can access them. My system can even detect Win7 in UEFI mode and will begin to boot to that OS (but of course, freezes at the logo screen because Win7 won't run on UEFI). The BIOS detects both HDD's and diagnostics says that everything's fine with both, but when I try to boot into Win7 in Legacy mode I get a no boot device error.

I've run the Windows7 install CD to try to run diagnostics and repair startup files, but all the diagnostics, including chkdsk, come back with zero issues, except 0x01f and 0x495 which only says that something was changed, but nothing specific...

I can't tell if the problem is with my startup files, MBR, or BIOS...

I've already backed up my Win7 HDD, but I'd rather not have to reinstall Windows cuz all my gaming stuff is on that HDD...

Can anyone help?

Answer:Dual-Boot Win7/Win10 on seprt HDD's - Both HDD's detected, 7 wont boot

Hi and welcome to SevenForums,
Dual booting with all hdd's connected can be problematic
I personally use one of these to simplify the task after many mishaps dual booting on the same disk.... I never found a better/ more reliable way other than this,
Amazon.com: Vantec 2.5-Inch Dual Bay Trayless SATA III - 6G Mobile Rack (MRK-225S6-BK): Computers & Accessories

Installing each os you'd want to remove the other disk completely so each os would have it's own boot loader.
Even though 10 can access win-7 I would not do it this will often trigger check disk to run in win-7.
Not to mention Fast start in win-10 will trigger it too
Fast Startup - Turn On or Off in Windows 10 - Windows 10 Forums

So yes disable fast start in win-10 is a must do.
Also for good measure disable fast or quick start in your bios too.
I would not share data disks either.

I'm not sure if I'm posting this in the right place, so I apologize if I'm not. But I have a HUGE problem. I have a Gateway laptop that's only about 5 months old. It has Windows 8 on it, and when I started it up this morning, I saw the Gateway logo, and then I kept getting an error message that said 'windows boot manager, boot failed, press ok to continue', which I did, and then got an error message saying 'no bootable device found, press any key'. I pressed ok, and then it took me to the boot option menu, which only gave me one option that said 'windows boot manager
(wcd wd3200bpvt-22jj5t0). When I press this option, it takes me back to the same boot manager error message.

I've tried hitting F12, and it just gives me the boot option menu like I described above. I get nothing pressing F8. If I press F2, I get the InsydeH20 Setup Utility. Under the security tab, it will only allow me to select the 'set supervisor and HDD passwords(there's currently no passwords listed for these). Below it has the option to erase all secure boot setting, select an UEF1 file and restore secure boot to factory default, but it doesn't allow me to go down to any of these options.

I'll be honest and say that overall, I'm not a fan of Windows 8.. it's so different from all of the previous OS's, which I was fairly adept at navigating through in order to troubleshoot when I needed to.. but I am clueless as to what to do with this problem, and have spent hours googling possible solutions, bu...

Answer:Help! error 'windows boot manager, boot failed!

Sure sounds like your hard drive may be failing or your boot sector is corrupted. However, since your laptop is only 5 months old, I assume it is still under warranty. With that said, I would recommend that you work this issue through Lenovo support so they can identify the source, authorize a factory service call (if covered), and/or authorize the shipment of any replacement parts (if required). Good luck.

Hello,

I have been using windows xp for a long time. I have two actual HD, one partitioned into 4, and another without any partition, giving me a total of 5. I was using two instance of windows xp installed in drive C and another in drive E (both are actually located in just one HD, but the other HD somehow got in between the two)

I finally decided to change the windows xp in drive C into windows 7. After installation, my previous option of choosing between which windows xp to use no longer appears and it goes straight to my new windows 7. I tried these four command :

bcdedit /create {ntldr} /d "Windows XP"
bcdedit /set {ntldr} device partition=E:
bcdedit /set {ntldr} path \ntldr
bcdedit /displayorder {ntldr} /addlast

So now an option appears before loading any windows but whenever i try to go to windows xp, it cant. It seems like i need to do more bcdedit.

Please help. Thanks!

Deggen

Answer:Dual Boot ( Xp professional Setup with Win7 ) in boot menu

Please post back a screenshot of your full Disk Management drive map with listings, using Snipping Tool ni STart Menu.

Do you remember which partition you tried to install XP upon? Normally you would just delete that partition in Disk Management, providing it is not already System Active. So let us see the Disk Mgmt screenshot, and tell us what is on each partition.

EasyBCD does not get rid of the partial XP install you have on there, just the boot listing. You still need to find and delete it from where it was installed.

Today I installed Windows 10 on my machine (ASUS N55SF laptop) for the first time on a separate hard drive. Now I have Windows 7 on my main hard drive and Windows 10 on my new drive (the latter being an SSD one). After installing Windows 10, I got a new boot option in my BIOS called "Windows Boot Manager" which is set as default, but it runs Windows 10 directly, I can't see any boot manager (I can assure "Windows Boot Manager" behaves this way because my BIOS lets me override the boot option, so that I can directly run any boot option, and this is probably the only way I can run Windows 7 currently).

If I go to Start → Advanced system settings → Startup and Recovery → Settings, I only see Windows 10 in the "Default operating system" drop-down menu, while I only see Windows 7 if I do this while on Windows 7. It's like the two OSs are not completely aware of each other.

Sorry if this was asked already, but couldn't find any similar thread.

Answer:No Windows Boot Manager on dual boot system (7 & 10)

You probably installed Windows 10 to the unallocated space on the SSD and let it create it's own partitions? When you do that, Windows 10 also creates it's own completely separate boot partition and boot files. You will just have to add the entry for Windows 7 to the new BCD store created on the SSD when you did the clean install of Windows 10.

If you had created an empty, NTFS formatted partition on the SSD first - and point Windows 10 to the already created partition, then it would have picked up on the Windows 7 boot files and just added the Windows 10 entry to those instead of creating new boot files.

There is a bcdedit command (I think) that will add the Windows 7 entry to the new BCD store, but will have to wait until at home to figure out what it is.

You can also use EasyBCD to do it, or Macrium Reflect Free (at least with the rescue disc version).

I can't boot into my xp drive from my Dual boot system. Primary and default boot is Win7 Secondary boot is WinXP. Both OS's are on separate drives. When I try to boot into the XP drive My error msg says:

"Windows could not start because the following file is missing or corrupt: <Windows root>\system32\hal.dll. Please re-install a copy of the above file."

So far to this this I have reinstalled a Norton Ghost image of Windows 7. No Joy. I also tried to fix the boot sector from Windows 7 by using the repair function when installing the operating system. No Joy.

Evidently there are some other commands could use from the command prompt? Would they help. I have been using Windows since 1998 but I never learned the boot sector very well and am lost when trying to fix it.

WIN7-XP DUAL BOOT FILES - to save to backup

I have win7 and XP as dual boot on same HDD. WinXP installed first. Works fine.

I use a backup/restore program to make images of each O/S - seperately and regularly.

However, it's not made for a dual boot machine according to the manufacturer.

When I restore Win XP, it works perfectly every time, so far.

However, when I restore Win 7, it refuses to boot into Win7 and has to be repaired with the original Win7 disc.

I can always get into either XP OR Win7. So a copy of the relevant boot files for each system, (copied and saved onto each O/S), could easily be pasted back into the partition that fails to boot -by doing it from within the O/S partition that will boot.

Can anyone tell me what are the relevant files for each system please (and where to find them) so I can copy & save them onto each O/S?. I can then easily restore them after an image restore that won't boot.

Thank you in anticipation.

I have a win7 and xp dual boot. They had been working fine, until one day I couldn't get on XP anymore. It'd just freeze while loading, whether it is safe mode, normal, you name it.
I had to do a system restore on the Win7, because of a video card problem.. now I can't get on it either. It works 1 out of 50 times. After doing more and more restores and trying to go in safe mode etc etc..

All that aside, for some reason now I can't seem to boot anything out of my CD Drives. I switch up the order, have switched them, tried only one, switched IDE cables, they work on windows.. they just don't seem to boot anything. I've tried several self boots dics now. Nothing.
Any idea on how this issue? I certainly appreciate it.

Hi there, I have a about 1 year old Lenovo Ideapad Z510.I was playing the game Counter-Strike: Global Offensive, and my screen suddenly froze. I couldn't even do ctrl+alt+delete. So I turned off the computer, but when I tried to turn the computer on again, this message came:I've looked through some of the forum threads to look for a solution to this, and some of the following said you had to go into the BIOS and change to Legacy BIOS boot. But that neither works. So whenever I try to move on from there, it says: "Boot device not found, insert boot device and press any key to go on". Afterwards if I press a key, I come up to a loading screen which says: "Loading files". After some minutes, this message comes up:I have never changed any Hardware or Software inside this computer, and I am not very good with the insides of a computer, so I would like to avoid having to take off the whole back of the computer just to change some parts. So does anyone have any idea of how to fix this? I currently live in Norway, but I bought this computer around easter 2014 in Singapore.

Answer:Windows Boot Manager boot failed

That simply meams that you have  boot failure. The first picture tells you the pocedure to follow to repair such a poblem. The second one tels you that you may have crashed hard drive and it is no longer accessible. Do the procdure as instructed by googling Microsoft media Creation tool to download and burn the Win 8.1 installer into a pendrive or dvd.

I can't boot into Windows. I don't want to have to restore the computer to factory settings and lose all my data. This all started with Windows updates that failed to install. I could not get into Safe Mode and tried several things as I mention below, including using the software of Easy Recovery Essentials, which made things worse. I emailed NeoSmart twice and have gotten no response.

Other than restoring the computer to factory default, is there another option, such as getting the Windows ISO and reinstalling Windows?

Here is what occurred in full detail.

I decided a few weeks ago to download multiple Windows updates. Most of them were installed, but to complete the installation for some of them, Windows said it needed to be restarted. Because I had multiple programs, folders, and files opened, I chose not to restart my computer then. I decided this past Saturday to finally restart my computer so that these updates can be applied. I was closing open files, folders, and programs. This was taking a long time because I had multiple things open and also because the computer was running sluggishly. After having a majority of things closed, I got impatient and decided to hold down the power button to shut off the computer. I turned the computer back on and windows began to apply the updates prior to fully booting up (I'm referring to the blue screen that shows the percentage of an update or updates being applied before one is taken to the desktop). Windows then sh... Read more

Firstly may I apologise if I have submitted my problem in the incorrect Forum, my symptoms seem to spread across a couple of areas.
I am operating a 1 TB drive with Windows 10 and 7 in a Dual Boot configuration on my desktop PC, the win 10 is an on-line downloaded upgrade from win 8.1, which was also an on-line download. All as been running well since win 10 was launched. I use win 10 for my Admin and Image Storage and manipulation and Win 7 for Flight Sim.
Yesterday afternoon I restarted my PC from Win 7, the PC rebooted to the Win 10 sign on screen but it was in a frozen state, there was nothing I could do so I pressed the PC reset button. It did not reboot to the Dual Boot screen, but presented me with a Blue screen headed 'Your PC needs to be repaired' followed by reference to:

Hello All,
I'm having a heck of a time trying to figure this one out so I came here for help.
Background:
I had a dual boot system with XP Pro and Vista Ultimate 32bit everything was great.
I decided to try the Win7 RC but I needed a new drive due to lack of space.
My original drive is IDE, I bought a SATA drive and moved the OS's to the new drive.
I wanted to keep the old drive in system for storage so I formatted it and changed BIOS boot priority.
After fixing some minor issues with drive letter assignments due to the fact the bios reads the first and second IDE channels first then SATA.
I was all ready to install Win7 RC on an unallocated 100gb section of my new drive.
Note: that the old drive has a single partition formatted NTFS but is currently blank.
And I did follow the "Golden Rule" of installing the oldest OS first when I set up the computer in the first place.
The Install went fine.

Now for the problem.
Win7 did not add an entry into Vista's boot manager so no option to boot into Win7 without the install disk in the drive.
I used EasyBCD 1.7.2 from within Vista to add an entry for Win7. But when initially added easyBCD assigns the drive partition a drive letter that I don't have.
Therefore the entry does not show up on reboot. I changed the path to the correct drive and then the entry does show up on reboot.
But when I select Win7 the boot manager refuses to load Win7 saying that "cannot verify the digital signature of the file winload.exe"

I want to run Red Hat 7 on my comp with Win ME.I need a Bootmanager. Has anyone any ideas of a free one that will do the job.

Answer:Boot Manager And Linux for Dual Boot

8.0 and 9.0 are updates from 7.0 as i see it.So 8.0 or 9.0 would be better. 9.0 has support for USB whereas 8.0 does not (without adding it which requires some knowing about Linux to do).You can download Linux... click here 8.0 and 9.0 have a boot mamger/laoder which you can choose you to install.

hi all,

I'm having a problem every time I power on the system. I'm dual booting vista ultimate with win 7 build 7100; with vista I have no problem, but with 7 every time I start the system the first boot attempt gives me the error 0xc000000e after the boot manager display: "the boot selection failed because a required device is inaccessible".;after a reset the system boots 7 with no problems. Win 7 is installed in a brand new hd(seagate barracuda 1.5tb) and vista on a second hd. I've search the web for people with a similar problem with no success. I've tryed already many solutions but the problem persists(latest bios for the motherboard, latest intel sata drivers, etc). I'm hoping that this could be a bug in win 7 instead of a hardware failure for the hd. Again, the strange thing is that this only happen after the power on. After that first error, no matter how many reboots, the system always boot without problems.
thanks for any help

Answer:boot manager/dual boot error

I would recommend to format that partition completely (I use Acronis) and reinstall fresh, if it happens again try downloading the *.iso from the microsoft site and burning it a little slower, it may have just been corrupt... just trial and error.

After the expiry of the RC on my test PC I have recently purchased Windows 7 for my main machine, since it's so much better than Vista and I need (okay, want) the DirectX capability it affords. A fresh install was the ideal time for a spring clean as well.Being a skinflint Yorkshireman I decided to go for Home Premium and dual boot it with my copy of XP rather than pay for Pro/Ultimate with virtual XP. No problems getting this sorted - formatted hard drive (after imaging), partitioned equally, installed XP Pro on one and Win7 on the other.My problem, albeit a small one, is this: after the boot manager comes up asking which version of Windows to boot, if I select Win7 (default) the OS loading screen comes up almost instantaneously whereas if I select 'an older version' I get a black screen for approx 30 seconds before the XP loading screen appears. Once into either OS the PC runs flawlessly.I wouldn't have thought so, but does this have anything to do with XP and 7 being on different partitions? They are both on the same HDD (WD Raptor) but is the boot manager on the Win7 partition and taking a while to get its head around XP being separate? I also thought about the SATA connection being loose but it appears fine and I never had this delay prior to formatting (when I just had XP as a solo OS). I could understand if they both had a delay then it may be a hardware issue, but I don't know what it could be. Obviously specs can be posted if necessary, but I figure it's more the boo...

Hi
Sorry if this has been covered but for some reason I can't get the search feature to work.

I have had Vista Ult (C) and XP pro (D) working in a dual boot for a while now without issue. I decided to install Windows 7 on the Vista partition.

1. I backed everything up.
2. I booted to the Win7 disk, when it came to the partitions, I selected the Vista partition and then the format option. It completed in seconds.
3. I installed Win 7 on the newly formatted partition.
4. Everthing went fine until reboot, it now boots straight to Win 7 without a boot screen where I can select which OS to start.

I looked in System Properties > Startup and recovery, only Windows 7 is listed.

The XP partition still shows up in Windows explorer and Disk management. After much googling I have found plenty with the same problem but no answer.

Any help would be appreciated. Thanks in advance.

I found how to add XP to the boot screen from the sticky but when I choose XP from the list, I am asked to run recovery. Below that it just says File: ntldr

I bought this computer from a yard sale. It had windows Vista on it at the time and 6 user accounts. The accounts with administration rights were password protected. So since I didn't need any of the data, I wanted to do a clean windows 7 install. Well I tried and everything was working fine. Then it froze at 59%. It stayed there for an hour and then it said an error. Forgot the error code. I tried it again and same thing happened. However after this time, trying to boot up, it gave me the 0xc000000f error. I've tried to boot from cd and it won't let me now. Won't boot into hard drive. I downloaded hirens cd on a usb and finally got it to work but unsure how to use it.

Hi guys, I have just registered with this community because I am at my wits end with my pc and need some genius's to assist me...

I hope I am posting in the correct section - (it's difficult to know if it should be in hardware section or here)

Here is the back story.

My PC had a single hard drive with 300Gig. (I will refer to it as original HD64)
Windows 7 Ultimate 64 bit installed.
Worked fine for a year or two.
Eventually started crashing randomly, attempted lots of fixes but was reliably informed that it could be my hard drive.

I decided I would be best with a new HDD and a fresh install.
Bought a new hard drive. 250Gig (Will refer to it as new HD32)

Unplugged originalHD64 from sata cable and power.
Plugged in newHD32 into sata cable.

Inserted bootable USB flash drive with windows 7 Ultimate 32 bit on it.
Went through full install including partition creation etc.
Install crashed part way through but I think the dog knocked the power lead.
Restarted install.
Everything seemed to install fine.

Plugged in original HD64 into second sata slot.
Changed boot priority to New HD32.
