Hi, I got a Xubuntu installation on a ibook G4 here. Booting from CD and USB (open firmware and yaboot) wont work. Original OSX DVD says "Label error blah". And I can only boot it via yaboot. Pressing "C" will throw me to yaboot and using boot from cd at the xubuntu bootstrap will only boot xubuntu itself. I am at busybox now, as nothing else is on the HDD. Which whould be the easiest way to fully delete xubuntu (remnants) and the bootloader, so I will have the original MacOS Bootloader running on reboot again, so I can finally boot from DVD ? Already did NVRAM/PRAM Reset. Now I get the "Flashing Questionmark Folder"...lol :S Still booting from CD not possible. Even with Alt Key pressed, neither HDD nor CD show up. Open Firmware when using "boot cd" says "LOAD-SIZE" is too small. No matter what kind of bootable CD i put in.
