I have installed ubuntu ppc 8.04 to my G5 desktop (1.6).

I power up and hold 'alt' - I then have the onscreen icons for which os to boot. I have 3 icons: my Mac OS X partiton. my firewire external clone partition - and the linux os with the penguin(?) on the drive icon.

I choose the linux with the mouse then press the arrow to proceed. Computer then goes to the text screen. It tells me press 'L' or 'X' or 'C. I press L then it goes back to the icons - and so on.

Any ideas anyone?
