Cant Boot Into Windows 7, boot configuration data error (BCD)


  • When I try to boot, I get the following:

    The Windows boot configuration data (BCD) store file contains some invalid information

    Object guide: {B2721D73-1DB4-4C62-BF78-C548A880142D}

    Status: 0XC0000034

    Info the configuration for an element within the object is invalid in the Boot Configuration Data Store

    The associated windows boot leader entry may not be available for selection until the problem is rectified.

    Then when I press it again I get:

    Windows 7
    Object {727A4D21-3E16-11DE-ADD4-C3E35E64B4}

    I am stuck, cant boot, got to system restore, it completed to an earlier date, but got the same stinkin message

    I have the original Windows 7 DVD and can boot to that.

    ANY HELP on this would be greatly appreciated. Im out of my computer till I get some help!

  • Thanx but this step by step is not written very clearly. Could someone kindly make it simple for us laymen:

    section 8 and 9 read

    8:Type the following command, and then press ENTER

    bcdedit /enum all

    In the Windows Boot Loader section of the output from this command, note the GUID that is listed for resumeobject . You will use this GUID later.

    9:Type the following command, and then press ENTER

    bcdedit -create {bootmgr} -d "Description
    Note Description represents the description for the new entry.

    DO I type Windows Boot Loader?

    And are we supposed to type {bootmgr} as well??

    Any help would sorely appreciated

  • Carey I tried this repair and got no where. I got confused on what step 9 means. Could you kindly let me know what "description" means and if i am supposed to type {bootmgr}

  • "Description" is the text which will appear in the boot menu for the given OS.
    It can be arbitrary. E.g. "Windows 7 RC".
    "{bootmgr}" is to be typed verbatim.

  • Thank for this. However when I typed "Windows 7 RC", I got the following:

    "An error occurred while attempting the specified create operation. The specified entry all ready exists. Cannot create a file that already exists."

    So then I tried "Windows Boot", same thing....

    Seems I need to first delete the old BCD then create a new one correct?

    There is nothing in this step by step that seems to tell me how to do this.

    I am still getting the same error code upon reboot.

    But this time it reads on the second screen:
    Windows Resume Application

    When I got to Windows Startup Recovery it stated it found a problem and would attempt to correct it:

    The Following Start up options will be added:
    Name: Windows 7 Ultimate (Recovered)
    Path: Windows
    Windows device:Partition:c (305234MB)

    A copy of current boot configuration will be save as: c:\Boot\bcd.backup.0003

    If any of this can help, pleaselet me know what to do. I still cant boot into windows.

    Thanks a millin!

    Yes, it seems the file boot\bcd is already messed up enough (because
    3 copies of it are backed up up to now).

    So, before applying "Method 3" from the cited link it will be useful
    to rename the file boot\bcd to say boot\bcd.old (as was suggested in "Method 2").
    By the way, if You know the letter assigned to Win7 installation partition while
    booting from installation DVD (presumably C:) You can skip steps 3 to 7 of Method 3.
    Just press Shift+F10 instead and the command prompt will appear, where
    You can type directly the command bcdedit /enum all from step 8, etc.

    By the way, there is another method of restoring the boot configutration,
    not described in the above link. It seems to be the most direct one.
    Boot from DVD, press Shift+F10, then run the command bcdboot C:\Windows.
    (supposing the drive letter of Win7 partition is C:). The command will replace
    the corrupted boot\bcd file with the newly created default template..
    That's all. After the above command will be executed, You can restart the computer
    and see whether this method did the work.

  • Thanks for this, however i get the following reply when using the rebuildbcd command:

    Successfully scanned windows installations
    Total identified Windows Installations: 0
    The operation completed successfully.

    Also, I no longer have a BCD file in my C:\Boot dir just a bunch of BCD-Backup.0001 -0004

    This is getting hairy

    Should I use any othe other buildbcd commands?


    ScanOs (I did this and it also told me I have no Windows on my system)

    Oh and the direct fix bcdboot c:\windows comes back ok, but when I boot my machine, It no longer gives me the original error, but snags on booting and I get the same repair options menu., then when I get to system repair, it tells me the boot file needs ammending, but it cant do it automatically...

  • I get the same thing but my Object GUID is different it is {c8f77482-f365-11df-a3cb-baf23602dc87} will the same steps apply to fixing this as well?
