So I pulled out my 800 MHz G4 the other day to force update to Leopard. I booted it into Target Disk Mode, wiped the hard drive, and copied my PowerMac G4 (1.25 GHz)'s hdd using Carbon Copy Cloner. I then ejected the iMac and attempted to boot up. It powered up, but instead of showing the grey Apple logo, it showed the error folder that flashes between Finder and a '?' I tried booting it from the disc drive too, but it won't even open. I get the impression that the iMac is not recognizing anything on the IDE cable. What should I do now? Is the problem software, or hardware? How do I fix it either way?
