I have an ancient iBook G4 with the original OS 10.3 discs. Today, for the first time since I can remember, my laptop started locking up and completely freezing (no beach ball, just an utter freeze that requires a manual restart) so in a last-ditch effort to save it, since I just can't afford a replacement right now, I'm trying to reinstall the OS. The first time I managed to successfully boot from the CD and everything was fine, until it got to 61% on the installation disc check. Then it froze completely and I had to manually restart again. Now it will not boot from the CD at all - the drive does seem to try to initialize it, but eventually it just sticks on a blank blue screen and the CD drive stops spinning. Does anyone have any ideas on how to get the poor thing running again? Can I do a safe mode boot or anything like that?
