Holy forget.
It didn't install properly. It's really forgeted up...
The iMac G4 does not support GUID Partition Tables. In order to install Leopard on an intel Mac, you need to make your hard drive partition a GUID partition table. You don't need to do this on a non-intel Mac.
So here's where it goes wrong. Because I was installing Leopard from an Intel Mac on the hard drive of the G4, it made me make the HDD a GUID Partition Table.
And like I said, the G4 does not support GUID Partition Tables. So it didn't work. It just made the HDD nothing.
So I've come up with a clever theory; I should be able to install 10.2 on the G4, then through Firewire run the disc drive off of the Intel Mac. This way it won't ask for a GUID Partition Table.
IF ALL ELSE FAILS, forget it, I'm putting Tiger on it and bedonewith.
