Hi, I have a secondhand iBook G4 and a few days ago it stopped booting up. It will load the apple screen with a loading circle and then switch to a blue screen with a loading circle and won't go any further. I tried to reinstall OS X by inserting the cd and holding down "C". When I do so it works up until the "Select a Destination" screen where it doesn't show my hard drive. I went into disc utility and my hard drive is shown there but I don't know what to do to make it show in the "Select a Destination" screen. Help? Anyone?
