im trying to boot from the disk and it goes to the OS. I'm trying to reinstall os x 10.3 from 10.4. Perhaps I have to download it from the os c 10.4 disk? I'm trying to boot up from the original disk one. EDIT: Ok, I was using the wrong software disk and not the actual oS X disk. Mods, you can delete this or keep it incase others are doing the same thing.
