Alright... I have a bit of a problem here. I need to format the hard disk of my Mac computer. Of course, I don't have install discs, or anything that can help me. I do, however, have an external drive, that now has a .dmg file of my hard disk on it. What I want to do is start the computer into single user mode, mount the external drive, then mount the image onto the external drive, then format the internal hard disk and copy the files from the external image to the internal hard disk. I hope this makes sense to whoever is reading this. Thanks in advance.
