Hey I have a Powermac G5 and I wanted to try out Ubuntu 11.04 and so I burned the iso image from there website to a CD R using Roxio Toast. And then I inserted the disk and restarted while holding "C" and it won't boot from the disk! I also tried holding ALT but, it won't show Ubuntu disk. I tried youtube but, all they show me is how to do it in VirtualBox and VMware. I have OS X Panther and it is getting old! There is nothing left for 10.3! And I can't install Leopard because it is a DMG file ( I got it legally ) and I need to make another Partition but, I can't figure out how. So if someone could help find out why it won't boot from Ubuntu I would be very thankful.
