My computer HD failed and I cant start my macbook at all. The computer boots and shows a question mark on a folder and the HD clicks so I assume thats the problem. I'm getting ready to order a new one and I can't find my original install disks. Can I do a fresh install of the OS on a new HD with just the Leopard install disk? I have a set of Mac Pro install disks, but don't know if they will work (missing divers?). Anyone know?
