    How to Use BitLocker Repair Tool to Recover a Drive in Windows 7 and Windows 8


    information   Information
    The BitLocker Repair Tool (Repair-bde) is a command-line tool included with Windows Server 2008 R2, Windows 7, Windows Server 2012, and Windows 8. This tool attempts to repair or decrypt a damaged BitLocker-encrypted volume using the supplied recovery information to reconstruct critical parts of the drive and salvage recoverable data to another volume.

    This tutorial will show you how to use the BitLocker Repair Tool to recover your data from a damaged encrypted operating system (OS) drive, fixed data drive (ex: internal volume/drive), or removable data drive (ex: USB drive) in Windows 7 and Windows 8.

    You must be signed in as an administrator to be able to do the steps in this tutorial.

    Note   Note

    • You must have at least one of the following for the BitLocker encrypted drive:
      • Password
      • Recovery key
      • Startup key .BEK file location

    • You will need to have an empty output volume (drive) of equal or larger size than the damaged BitLocker encrypted drive. The contents of the output volume will be completely deleted and overwritten by the decrypted contents of the damaged BitLocker drive.

    warning   Warning
    The BitLocker Repair Tool should only be used as a last resort when you were unable to decrypt or unlock the encrypted drive using either the password, recovery key, USB flash drive, or BitLocker Recovery.

    Tip   Tip
    If you were signed in to your Microsoft account when you encrypted a drive with BitLocker, then you can get your recovery key from your OneDrive at the link below.


    Microsoft account: BitLocker recovery keys



    EXAMPLE: Before and After using BitLocker Repair Tool
    NOTE: In this example, the BitLocker encrypted drive is F: and the output volume is E: .

    Here's How:

    1. Do step 2, 3, or 4 below depending on what you would like to do.


    2. To Use the Password in Windows 8
    NOTE: This option is only available in Windows 8, and would be for an OS drive, fixed data drive, or removable data drive that you have configured to be unlocked by a password.

    A) Open an elevated command prompt.

    B) In the elevated command prompt, type the command below, and press Enter. (see screenshot below)

    repair-bde F: E: -pw -F

    Note   Note
    For only items in red in the command above:

    Substitute F for the drive letter of the Bitlocker encrypted drive. Not the last F.

    Substitute E for the drive letter of the output volume you want to have the contents of the Bitlocker encrypted drive decrypted and copied to.



    C) When prompted in the command prompt, type the recovery password for this encrypted drive, press Enter, and go to step 5 below.
    NOTE: You will not see the password as you type it.

    3. To Use the Recovery Key in Windows 7 and 8
    NOTE: This would be for an OS drive, fixed data drive, or removable data drive that you still have the recovery key either saved to your Microsoft account, saved to a file, saved to a USB flash drive, or printed.

    A) Open an elevated command prompt.

    B) In the elevated command prompt, type the command below, press Enter, and go to step 5 below. (see screenshot below)

    repair-bde F: E: -rp BitLockerRecoveryKey -F


    For example:

    Code:
    repair-bde F: E: -rp 261173-522599-237072-583517-442068-316811-199375-623755 -F
    Note   Note
    For only items in red in the command above:

    Substitute F for the drive letter of the Bitlocker encrypted drive.

    Substitute E for the drive letter of the output volume you want to have the contents of the Bitlocker encrypted drive decrypted and copied to.

    Substitute BitLockerRecoveryKey for the actual 48 digit recovery key for the encrypted drive like below.

    Saved to USB or File:

    Click image for larger version

    Saved to Microsoft account:

    Click image for larger version

    4. To Use the Startup Key in Windows 7 and 8
    NOTE: This would only be for an OS drive that you have configured to be unlocked by a USB flash drive.

    A) Since you will not be able to boot from the OS drive, you will need to first connect it to another Windows Server 2008 R2, Windows 7, Windows Server 2012, or Windows 8 PC.

    B) Open an elevated command prompt in the other PC.

    C) In the elevated command prompt, type the command below, press Enter, and go to step 5 below. (see screenshot below)

    repair-bde F: E: -rk I:\StartupKey.BEK -F

    For example:

    Code:
    repair-bde Z: E: -rk I:\AFA58D77-94CD-4300-8009-68B36AE53276.BEK -F
    Note   Note
    For only items in red in the command above:

    Substitute F for the drive letter of the Bitlocker encrypted drive.

    Substitute E for the drive letter of the output volume you want to have the contents of the Bitlocker encrypted drive decrypted and copied to.

    Substitute I for the USB drive letter that the startup key has been saved or copied to.

    Substitute StartupKey for the actual file name of the startup key for the encrypted drive like below. The BEK file (startup key) will be a hidden protected OS file.

    Click image for larger version

    5. When finally successfully finished, follow any given "ACTION REQUIRED" first. For example, to run chkdsk on the output volume before opening. (see screenshots below step 2, 3, and 3 above)

    NOTE: The BitLocker Repair Tool may take a long time to finish, but you will still be able to use your PC during the recovery process. Just do not turn off the PC until it has finished.

    6. You will now be able to open the output volume (ex: E) to view the decrypted files from the BitLocker encrypted drive (ex: F).



    That's it,
    Shawn

    Hello Heenasar, and welcome to Eight Forums.

    Most likely you may have lost everything on that drive due to the power outage corrupting it and your BitLocker password.

    Unless you saved your BitLocker recovery key to another location as a backup, then you lost it when your formatted Windows 7 to install Windows 8.

    About all you can do is try to unlock the drive with both your old or new Bitlocker password using step 2 in the tutorial to see if either will work.

    ....or by trying step 2 in OPTION TWO of the tutorial below.
    If you are unable to, then I'm afraid that you may not be able to unlock it, and lost the contents.

    The whole point of BitLocker encryption is that without the password or recovery key, access will not be allowed.

    You will be able to format the drive to be able to use it again, but doing so will also delete all data on the drive.

    I'm sorry, but you will most likely not be able to recover any data without these. Especially since you lost power in the middle of changing the BitLocker password.

    I hope you had backups of your data to restore from.

    Unfortunately, if you don't know if you have a backup, then you most likely don't since you would have needed to manually back them up.

    If you do not know that you have a backup, then you do not have one since you would have had to created a backup to have one. If you created a backup, then you would know that you had one.

    You cannot create a backup after the data is gone. It must be created before.

    Next time, please be sure to save a copy of your BitLocker recovery key and password in a safe place in case you may need it like in this case. In addition, you should always have any files that you do not want to lose backed up to a safe location as well.
