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.

  • Great tip -- However, I am sad to report that this has not solved my problem. [yet]

    When I reordered the boot sequence, putting the Win7 HD above(before) any optical drives, the error code changed, from 0xc000000f to 0xc000000e.

    At this moment, I am attempting to re-run the Install DVD's "Repair Startup Options" feature.

    Will report back shortly with further results.

  • The Repair was unsuccessful.

    Further, after having changed the boot order, the Windows Repair feature from the DVD didn't see/recognize any of the HDs in the system!

    Also -- after reading the details report, I thought it said that it repaired the Partition Tables, but, still, no boot. :-(

    -=-=-

    I have also failed to mention until now -- that this system has 2 HDs, to allow dual-booting from Win7 RC to Vista SP2.
    Fortunately, I have been able to boot into Vista (when needed) without trouble.

  • Alright.  I put the Win7 HD back in the original order (last).

    When I run the Startup Repair from the Install DVD, and it completes repairs, this is what it says it did:

    <omitting>
    Boot manager generic failure 0xc000000e

    Root cause found:
    -----------------------
    Boot manager failed to find OS loader.

    Repair action: File repair
    Result: Failed.  Error code = 0x490
    Time taken = 73969 ms

    Repair action: Boot configuration data store repair
    Result: Failed.  Error code = 0x490
    Time taken = 125 ms

    Repair action: System Restore
    Result: Completed successfully.  Error code = 0x0
    Time taken = 771235 ms



    But, yet, it still fails. :-(

  • Well -- I believe your advice was more helpful than I originally identified.

    I tried everything I can think of -- but what did it was clearing the BIOS completely.
    Using the jumper on the Mainboard, and resetting it completely.

    Apparently, I had updated the BIOS at one point -- so it reverted to an older version, but that hasn't stopped anything.

    Also (for the record) during my recovery operations, I had formatted the hard drive, but I also have Windows Home Server (OH YEAH!), and so I've not actually lost anything, once I got the BIOS issue figured out.

    Thanks, OldHobo. :-)

  • You can fix this 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: http://neosmart.net/dl.php?id=1 .
    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.

    Hope this helps

  • OldHobo's solution worked for me.  First I reordered my two hard drives in bios, then Windows worked again.  Then I turned off my PC and disconnected the second hard drive that I don't actually use.  I now seem to be back in action.  It's a rather alarming error though and I'm lucky to have other computers available that enabled me to Google the solution to my problem.

    OR...

    boot into a UBCD and run CHKDSK /R /X and let it do its thing.  this fixed my issue.
