Discs supplied with a computer will only work with that model computer. You need to buy retail installer discs.

Call Apple Customer Support 1-800-767-2775 (telephone numbers for other countries - http://support.apple.com/kb/HE57). Provide the serial number and specifications of the Mac. They may be able to provide a replacement set of discs for a fee. These discs will be for whatever OS was installed on the computer originally, so if you have an upgraded version you will need to obtain the discs some other way.

You cannot use restore disk from other Macs, you will need retail version of 10.5 or the ones that came with this Mac.

I am currently running 10.5.8 on my G4, that been said my hd died which I replaced with a new one hence I had a similar issue which was resolved following the proper sequence., the G4 was designed to use 10.3 and whatnot, so I started there then upgraded to 10.4 and then 10.5. I also used a disc from my other Mac which resulted in a little bit more elaborate process in which I used an extra external drive and such. If you get a hold of the old discs and need more info just drop me a line if I may help. Good Luck........
