  • Hello,

    You can try repairing Windows 7 machine. Let us know what issue you're facing on it. If you repair Windows 7 machine, you can then unlock and decrypt HDD to use it with Windows 10.

    Regards.

  • In that case, the only option seems possible to me is to format the HDD and then you can use it. It is obvious that you can't encrypt it with Windows 10 Home as it doesn't have BitLocker capability.

  • The recovery key would work anywhere. If it says invalid key and you made sure you typed it correctly, you can only try and use another machine to decrypt the drive or boot windows 10 setup to have kind of a different system and there use the command line to unlock it

    ->boot setup

    ->press shift F10 when at the language selection so that a command prompt will appear

    ->use the command

    manage-bde -unlock d: -rp 111111-222222-....(substitute these numbers for you 48-digit recovery key)-666666

    If the external drive does not have the letter d:, try e: and f: and g:

    if it succeeds for example with d:, use the command

    dir d:

    to see the folders.

    If these appear as expected, just disable the protectors using

    manage-bde -protectors -disable d:

    Then reboot (close anything) and your drive will be accessible, ready to set a new password and recovery key. On an elevated command prompt, use:

    manage-bde d: -protectors -add -pw

    After setting that password, exchange the recovery key:

    manage-bde d: -protectors -delete -type recoverykey

    then add a new one:

    manage-bde d: -protectors -add -rp
