Used computer with bitlock?

Abagail Curtis 1 Reputation point

So I recently bought a Windows Surface Pro and I have done just about everything that I can do to try and get this bitlock off. When I bought it, I was unaware of the bitlock. Is there a way I can get it off with help from microsoft? Or is it just trash? I spent my money and now im wondering if it was even worth it.

    If you cannot get the bitlocker key from the previous owner, you will need to wipe the disk and reinstall windows.
    To do that:

    1 download the media creation tool from Microsoft and make it create an USB setup stick
    2 boot from that stick (you'll need to use instructions here:
    3 when setup has booted and you are at the language selection screen, press shift F10 so that a command prompt opens.
    4 on that command prompt, launch the following 3 commands one after the other:
    sel disk 0
    5 now after these commands succeeded to clean the disk, close the command prompt and proceed with setup.

    A final gotcha: on a surface book2 (which is the only surface device I ever reinstalled), I witnessed a fun-fact: after reinstalling, no keyboard driver was loaded, so the keyboard did not work. I could complete setup only with an external USB keyboard and had to load drivers through windows update.

    In case it is a used device, we advise you to format the system and reinstall Windows.
    The system might be corrupted, and you will face other issues, you may get the Windows installer media from:
    And boot into your device and reinstall Windows.
    Make sure you are downloading the correct edition of Windows (e.g., Home or Pro).
    You have to boot with USB.
