    Question

  • Hi folks,

    Just came across a scenario for one of our customer. 

    Trying to recover data off a drive that is bitlocker encrypted. No recovery key available to get pass bitlocker and access the drive.

    Please advise if I reinstall OS preserving the old data in windows.old folder; will I be able to get the access the windows.old folder afterwards to get the data off it.

  • Hi,

    Didn't you remember the password? How did you save your recovery key?

    If you save it to this computer, it would be in your Windows.old file.  please check if there is a file saved your recovery key.

    It's 25 characters recovery key and save to a file when you enable the BitLocker. If it's not in the Windows.old file, you cannot get it back any more. Since then you cannot recovery your data.
