Hi, awhile ago I got an iMac from a friend of a friend. They didn't tell me what was wrong with it, only that it needed a new OS. It's a PPC mac and I wanted to try out Lubuntu linux (but I have OSX 10.6 if that doesn't work) But when I try to boot, I get a white screen, then after awhile a folder with a question mark appears. I tried holding alt(option) to boot, but the weirdest thing happens. I'm still in the same white screen, but I get a cursor. This is again with the Lubuntu linux disk. The OSX 10.6 disk just gives me a white screen and the folder. Is this a hardware issue or software? Because I tried booting Windows XP just for the hell of it and it actually went through the setup until the end. Any help would be appreciated. Thanks!
