Quite honestly, OS 9 is not this hard to install, I install OS 7, 8, and 9 several times a year, even in 2007.
Do you have a legitimate OS 9 disc? It's usually as easy as, like, putting the CD in, formatting the drive, double click Mac OS Install and let it do it's thing.
I can't fathom what you could possibly be doing it's such a simple process. But you can try these things:
- First, get the damn CD out! Hold down the mouse buttn when the computer restarts until it spits the CD out.
- Second, reset your PRAM, by shuting the computer off, holding down Command + Option + P + R, and turning it back on (still holding these keys) until it restarts itself a second time.
That's pretty much it. Installing OS 9 is really straightforward and easy, you shouldn't be having problems like this.
