I recently bought a macbook for my girlfriend. The guy I bought it from had taken the hard drive out because it was messed up. The Macbook wasn't in awesome shape, but it was OK. I've since replaced it. I got a new copy of Leopard, but when I put the disk in, it does nothing. The drive seems to be reading it. I've also put the disk image on my ipod and tried to take it off that. All the Macbook does is flash the folder with a question mark on it. I've tried resetting the PRAM and holding down D, C and T. Nothing seems to work. Does anyone have the slightest damn clue of what's wrong?
