*EDIT*
im in the disk utility menu trying to reinstall Mac OS X Lion. Its not letting me download it because my apple id does not have it bought and i cant use the previous owners because i cannot contact him due to personal issues. Is there anyway that i can use somebodys apple id that bought Lion? All i need to do is sign in so i can re install it then i will sign out and completely get rid of the account. PLEASE SOMEBODY HELP!
Also, i have a Mac OS X Leopard Disc but dont know how or if an install it because the system is running Lion.
Please Help, Thanks!!
