Hi. Starting last evening, I have been unable to make my G4 Powerbook with Tiger boot past the screen with the apple. I used the Tiger install DVD to repair the disk. It found problems, but thinks it fixed them. It still won't boot from the HDD. I think what I want to do is copy a few important files to an external HDD and then reinstall the OS, but I can't seem to do that through the disk utility, unless there's a way I don't know. It will let me look inside the internal, but that isn't helpful if I can't move anything elsewhere. Any suggestions?
