I installed Ubuntu on a PowerBook G4 and it only works about 10% of the time. For this reason I decided to re-install OS X, but my machine won't boot from CD. It also won't boot Ubuntu the vast majority of the time, so I'm kind of screwed.
After a ton of tries, I finally got my machine to boot a Linux command line.
Is there anything I can do at this point to make my machine more runnable, just for the sake of installing OS X?
