My iBook G4, running Tiger, is stuck in a loop. While trying to reinstall os x 10.4 I was instrucked to insert disc 2. So I did. Resulting message: "There were errors installing the software. Please try installing again." with "close" the only option. So I close. It spits out disc 2 and message pops up: "please insert dics 2 to continue installation." The only way out is to crash but there's not really any way out because, when I re-boot I get the "there were errors installing" message and around and around we go. I tried to boot to my hard drive from the install disc but it won't go there. I did the hardware test and it says all is well.
