Hey guys. I just got an IMac g4 from my school (they upgraded, and gave me an old one) and it turns out that the OS is not installed. I dont have the original 9.1 installation disk. i just have one that they gave me with it, along with an OS 10.0 installation disk. When i try to install OS 9.1, the installation gets to the Starting Up screen, and about a quarter of the way loading, it freezes. Ive tried restarting, and that still didnt work. I have no clue what to do
