My husband got a new surface so I got the old one .We factory reset it and now it's asking me for the bitlocker code, even when it says skip this drive and I go to reset the computer again it's still locked. It's no where to be found. It's not on his OneDrive account for microsoft. I know I can plug a USB with Windows 10 on it and download it and start fresh but I need a step by step on how to do that on a surface. I've only don't it on a PC many years ago. My surface has been useless for months. Any help would be much appreciated!
