More aboutlost locker
why did you reinstall windows? you lost the authentication key by doing so you might as well get a new drive because without a key you can't get in its a security measure there is no way around it and yea we dont offer help with passwords on forums
Lots of easier ways to prevent access besides complete encryption, look into that next time, much more recoverable.
Did you skip making the recovery key when bitlocker asked you to?
