I was here with Cammy when she was trying to boot up and install MorphOS 3.0 and Ubuntu 10.04 on her MacMini and PowerBook. Neither of them would finish booting either OS, even after we cleaned the lenses in the CD drives. They were still able to play music CDs and read files from CDs in OSX.
In any case, she ended up installing MorphOS from a USB stick with a custom boot.img file. Installed lightning fast from that too.
