"The boot selection failed

 because a required device is inaccessible" Windows 7/Vista error
Source

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

1. Insert your windows installation disc and restart your computer.

2. Choose your langugae settings, and then click next

3. Click "repair your computer."

Status: 0xc000000e

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


Then I tried to run the Windows 7 installation disk, I go to the cmd prompt and run the

Quote:
DISKPART
diskpart
list disk
select Disk X (X=disk where I installed all the OS, should be Disk 0)
list partition
select Partition X (X=partition containing OSX)

Virtual Disk Service error:
The pack is not online
and then i run the Bootrec /ScanOS, it came with 0 identified Windows Installations, this is why I come into the cmd prompt as I could not select the installed OS 
I've tried that from bootable cd to repair the install but the partition of windows7 is not recognized still.

Solution

I had the same problem - number 0xc000000e, after changing hdd physical order.

Download EasyBCD.


(It is required other Live Windows or brought disk to someone with Windows OR

run probably bcdedit command from recovery dvd_win7_disk)

Then look at your item which boot Win! My item had a record with unknown device or similar Deleted partition drive. I suppose correctly there must be something like C:\. 

So instead of delete that item I prefer added next and selected right drive for it. 

It can be one of C:\,D:\,E:\,... with your Windows directory (where you have installed it). More interesting is that it didnt have to be equal letter as it appears after boot in different computer, different hdd order, ...

After reset - booting without problems


You can do this easier by using Easy BCD. I had this exact same problem but I no longer have a copy of Windows 7 and Microsoft stopped the free download.
Download Easy BCD here: 

Once you have it installed start it up and click view settings. You will most likely see that it says 'Partition Deleted' or something to that effect under the Windows 7 entry beside 'Drive:'.
Click on 'Change Settings'. Under 'Entry-Based Settings', choose Windows 7 and change 'Drive' to the drive letter of your Windows 7 partition and then Save Settings.

When you reboot you should be able to boot into Windows 7 again.


Its a well known fact that if one or more required boot files are found to be missing or corrupt, a Windows system might fail to boot. Such problems can be resolved by using Windows installation disc. But still if it is not resolved, the the only solution remains is to install the operating system, which causes data loss.
Now, if no valid data backup is available, you need to use windows data recovery utilities.

Reasons:


  1. One of more Windows boot items, like MBR, BCD store etc., are missing or corrupt


  2. Incorrect BIOS settings for the boot device, usually hard drive. This might occur if you have recently performed some changes in system BIOS settings. 
Solution
If after changing the BIOS settings, Windows is unable to boot, then configure BIOS to default fail-proof settings and after that set hard drive as the primary boot device. And if it is not OK then we should repair Windows startup files using windows recovery environment as follows:


  • Insert Windows Vista or Windows 7 installation disc into the computer and boot the system


  • Press any key for starting the repair process when prompted for


  • You need to then select the time, language and currency and the desired input method


  • Click 'Next' and select 'Repair your computer' option


  • The 'System Recovery Options' dialog box appears, at which you need to select the Windows installation you need to repair. Click 'Next'.


  • You can then select the 'Startup Repair' option. Instead, you can also run 'Bootrec.exe' through 'Command Prompt'
If the above steps fail to boot Windows successfully, then it is suggested to reinstall the operating system and use your recent data backup to restore the lost data. If no data backup is available, use windows data recovery software for extracting the data. These software are embedded with high-end scanning algorithms. The software also enable you to perform comprehensive Partition Recovery in all cases of logical crashes.
Cause
The above error might occur due to any of the below reasons:


  • Incorrect BIOS settings for the boot device, usually hard drive. This might occur if you have recently performed some changes in system BIOS settings.


  • One of more Windows boot items, like MBR, BCD store etc., are missing or corrupt
Solution
If Windows is unable to boot due to changed BIOS settings, you should configure BIOS to default fail-proof settings and set hard drive as the primary boot device. If this is not the case, you should repair Windows startup files using Windows Recovery Environment as follows:


  • Insert Windows Vista or Windows 7 installation disc into the computer and boot the system


  • Press any key for starting the repair process when prompted for


  • You need to then select the time, language and currency and the desired input method


  • Click 'Next' and select 'Repair your computer' option


  • The 'System Recovery Options' dialog box appears, at which you need to select the Windows installation you need to repair. Click 'Next'.


  • You can then select the 'Startup Repair' option. Instead, you can also run 'Bootrec.exe' through 'Command Prompt'
If the above measures don't boot Windows successfully, you should reinstall the operating system. You should then use your recent data backup to restore the lost data. If no clean data backup is available, use data recovery software for efficiently extracting it. data recoveryutilities are powerful third-party tools embedded with high-end scanning algorithms. The software also enable you to perform comprehensive partition recovery in all cases of logical crashes.

"Repair your computer" F8 boot option not working

Status: 0xc000000e
Info: The boot selection failed because a required device is inaccessible.


 Start an elevated command prompt and type bcdedit /enum all
Attach the ouput of this command to your next post. Also, confirm that you have the folder C:\Recovery on your disk. You will need to enable the display of both hidden and protected operating system files in order to see it.
