Hi sorry if this has beeen covered before,but im new to macs, just got an emac and basically it wouldnt boot and now what i have is an empty hard disk(erased my osx install) that came with the computer and an OsX "boot cd" that i can boot to osx with. Ive tried to do a restore image with disk utility and simply draged the cd image to the source and my empty (mac osx partition) to the destination and it says it completes it. however when i restart, chnaging startup disk to hdd. it simply will not boot past the apple screen with the little black cirlce going round and round.Is it possible to copy the osx boot cd to the hard drive and boot from it? thank you please help!!!Ive tried other disk utilities but they cannot unmount or mount drive .
