Hello to all, this is my first post and i need a step by step on how to reload my operating system back to my macbook pro using my imac. The drive doesn't work in the macbook pro and all i get when i start up the macbook pro is the apple symbol and the spinning wheel for a few minutes then the macbook pro shuts itself off. I have hooked up the macbook pro to the imac using firewire and can see the macbook pro's drive on the desktop of the imac but don't know how to reload the operating system back to the macbook pro from the imac. Any help would sure be appreciated. Im kinda dumb to the Apple computers but trying to learn so please bear with me. Again thanks to everyone for any help.
