    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
