Hello,

If you check the BitLocker recovery key identifier on your Microsoft account, does it match that of the hard drive that you need to unlock? If not, check for other recovery keys on that account.

I hope to hear back from you.

Hi, check the Recovery Key ID shown when you try to unlock the old hard drive. Match that ID with the entry in your Microsoft account, then enter its 48-digit recovery key. Make sure you’re using the key for the old drive, not the laptop’s own drive.

If there’s no matching entry, check any other Microsoft account used on the original PC, along with any saved or printed recovery key. Please don’t post the recovery key here
