So I've been trying to install Ubuntu on my ibook (6.10 and/or 7.04) and holding C and I sit at the grey screen for a couple minutes, then osx 10.3.9 boots as normal. Holding down alt to get to get to the hard drive/cd selection screen I get the choice of wither, but when I click on the Linux icon, the colors on the screen distort and it stays on this menu.
Also, I am running the cd on a external usb (1.1 built in to ibook) cd drive due to the internal drive being dead.
I guess what I'm asking is: Is there any way to get this to boot from the cd or any other way?

Thanks in advance
