Then you need to find a way to work it out with him. This is between you and him at this point. Since it is impossible at this point to determine who has authotity of this machine it would be remiss of us to tell how to get into the OS.

Yep but that requires hacking in to the computer and chances are you probably wouldn't be able to. BTW Hacking and Cracking into a system is illegal.
