So what do you expect us to do? If you have none of the information in the above post well then I don't really believe this computer is yours. Who loses both their bit locker password and recovery key?
Wouldnt be very good encryption if you could just make a post stating you "lost" all your ways of unlocking the drive, and then have people tell you how to bypass it. Cant be done. Ask the person who owns it.
i forgot my bitlocker password and lost my recovery key
Then your data is completely, irrevocably, irretrievably, lost.
Just like if you took the drive out...took a boat ride 50 miles out into the ocean, and dropped the drive overboard.
