I received an iBook G3 dual usb from my friend after it stopped working. (500mhz, 128+256MB ram, 40GB hd) After working on it for a few days, I fixed the ati graphics chip problem that many ibooks have, and so now it will turn on fine. The problem is I cannot get it to boot off of the hard drive. It will boot off a live Ubuntu disk and run fine, and it will install both Ubuntu and os x, but after installation and reset, it will not boot. I can browse files on the drive when running off a live cd, so I think the hard drive is fine. It will also boot off my friends mac through firewire. Any help will be appreciated.
