alright, so i bought this iMac G5 off this guy, and it turns out he has his drive partitioned, one with OSX, and the other side with Tiger. Why? I don't know. Anyway, i dont want it partitioned, i want one big hard drive, how would i go about this, i wouldnt have a problem with reformatting the HD because none of the things on it are mine, but how would i back get OSX on it? it is running 10.5.8 now. any thoughts? thanks!
