Hello, i have an Ibook g4 and i am planning to put a Linux based operating system on it or rather install it. I have selected Ubuntu as that operating system. The problem is that my Ibook will boot only half ways and i can only only see a white screen with the apple logo and loading sign. After that it goes to a blue screen and freezes so i can't install Ubuntu as my full operating system and not a dual boot one since it will only boot up that far. Additionally i can't even get in to it at all so how can i install Ubuntu?? I do not have the Snow Leopard CD by the way. Please help me resolve this issue.
