Hi there, I have a MacBook Pro, which is not starting up. It is my sons, and although I am not completely computer illiterate - I am certainly no techie! It just didn't start for him once while I wasn't home so he tried to repair it himself - used disk utility and I think he chose Erase option before he worked out that he should have done repair. Since then, I have run disk repair, fsck and all the other utility options to get it to start. Disk repair comes back with no faults. It fails when I try to install Lion using the recovery option, and it fails when I try to start it from the Mac OSX Leopard discs that came with the laptop. I'd rather not take it to the repair shop - and simply blowing everything away and starting again is an option, as there is no especially important data on it. Can someone please help with either some new options to try or how do I simply erase everything and start again??? Very much appreciate any help !!!
