Windows 7 boot error c0000000e - The boot selection failed becuase a required device is inaccessible RRS feed

  • Question

  • Bootrec /scanos says no OS found. /fixmbr and /fixboot both run and complete but neither fixes the issue. The auto repair fails and also doesn't see the OS installation. That being said through the command prompt I can browse the drive and see all the Windows folders. Its something spyware related I just cant think of what to check. Ideas?

  • Hello,

    A Windows system might fail to boot if one or more required boot files are found to be missing or corrupt.

    Try this:

    1. First Load Windows Recovery from Windows 7
    2. Open Diskpart
    and make problematic partition Active
    3. Open bcdedit and you should get
    something like this:

    Windows Boot Loader
    -------------------
    identifier {default}
    device unknown
    <===0xc000000e problem!

    path
    \Windows\system32\winload.exe
    description Windows 7 (etc etc)
    locale
    en-US
    inherit {bootloadersettings}
    recoverysequence
    {e0025536-b36d-11de-aadd-ddc0b5870e2c}
    recoveryenabled Yes
    osdevice unknown <===0xc000000e problem!
    systemroot
    \Windows
    resumeobject {e0025534-b36d-11de-aadd-ddc0b5870e2c}
    nx
    OptOut
    hypervisorlaunchtype Auto


    4. Enter these
    commands:

    bcdedit /set {Your-OS-Identifier} device
    partition=X:
    bcdedit /set {Your-OS-Identifier} osdevice
    partition=X:
    bcdedit

    Where X: - drive letter with your problematic OS
    in Windows RE. You can find it by opening notepad and pressing save

    5.
    Reboot

    An alternative is to reinstall and to delete the partition in question as well (that is, COMPLETE rebuild).

    Please let us know how you go...

  • Niki - Where X: is the drive where the Windows folder resides?

    Dr.Dissector - you fix seems to be running from within Windows from a CMD prompt. I cant get into Windows. I am running this from the recovery option of a Windows 7 CD and i get no error.

  • Yes, C: is the drive which contains the Windows folder. Did the command repair the bad BCD files?
