Bitclocker doesn't unlock encrypted partition after Windows 10 Upgrade - No recovery key is available, only recovery password

    问题

  • Hello,

    I have a laptop HP 450 G3.

    The disk contains 

    a) Recovery partition

    b) System partition

    TPM is activated

    The Laptop wasn't attached to Domain.

    I was using this system for over 6 months without a problem and <g class="gr_ gr_25 gr-alert gr_tiny gr_spell gr_inline_cards gr_disable_anim_appear ContextualSpelling multiReplace" data-gr-id="25" id="25">i</g> was using only the <g class="gr_ gr_22 gr-alert gr_spell gr_inline_cards gr_disable_anim_appear ContextualSpelling ins-del multiReplace" data-gr-id="22" id="22">bitlocker</g> password to unlock it.

    My password is a 10 digit number, for example, 1234567890

    After I attempted a Windows 10 Upgrade to the latest version and turned off the PC the system now asks for Recovery key, which I don't have because Ι never used it before.

    All my files are in this partition, including the operating system and Ι cannot access it.

    I have also tried to unlock the drive with the manage-bde command but failed.


    I am confident that Ι types the password correctly since Ι was typing it for 6 months.

    What can Ι do to get back my data? Anyone that can help me please contact me

    I also tried the repair-bde command but with no success.

  • When you enabled BitLocker, there is a dialog ask you to save the recovery key:

    On a printout you saved

    On a USB flash drive

    In your Microsoft account

    You can get the BitLocker recovery key from above methods.

    If you have suspended BitLocker, you can resume BitLocker protection after you have installed the upgrade or update. Upon resuming protection, BitLocker will reseal the encryption key to the new values of the measured components that changed as a part of the upgrade or update. If these types of upgrades or updates are applied without suspending BitLocker, your computer will enter recovery mode when restarting and will require a recovery key.

    Try to degrade to previous Windows and unlock again.

    When you using repair-bde h: x: -pw to unlock partition, it's asking for the 48 digit recovery password not the user password.

    repair-bde
