Either way you need a password and acording to the OP's post he's saying a recovery key was not found on the usb device and naturaly it would't be on the device because it's password protected and to access it you need the password.
Is that the only reason you posted here to critique my post and try to prove me wrong ?
Didn't need to try. You quite frequently post without doing due diligence, just happens that this time it was so blatantly wrong that it required correction.
To the OP, are you running at least Windows 7 Ultimate? Anything lower (Pro, Home Premium, etc.) do not support Bitlocker.
