iMac won't boot from Tiger DVD, Difference between Intel/PPC?

[msdonb]

I have an iMac that had some corrupted data on the drive and therefore would not boot. The drive was reformatted/repaired and in doing so, lost the installed OS. I have a burned copy of the retail version of Tiger OS that I've been using on various PPC g4 macs, but for some reason the iMac won't see the disc as a bootable disc. I can boot TechTool pro and Unix, but have been unable to get this thing to load the OS. Is there maybe a universal boot disc that will load DOS that maybe I can 'jumpstart' the install? Also, when I boot the iMac in Target disc mode, with the Tiger disc in, the other Mac sees both the blank hd in the iMac, as well as the Tiger disc in the iMacs DVD-Rom drive? Strange? I'm wondering if there is a different version of Tiger that came with the iMacs? The disc I am using is 10.4.0. Any suggestions? Oh, and I've tried loading the OS from a different computer with the iMac in target disc mode... it has a red ! over the volume saying that it's not a bootable volume/mac cannot boot from this volume. Help please!?!?

Don't you have the original install disk for the imac, or the original retail 10.4?

Unfortunately, I have none of the original restore discs. The disc I am using is a copy of genuine 10.4 retail disc.

Located problem: Apple install discs are hardware specific, MUST use INTEL version of 10.4.4 with intel-iMacs. Retail copy won't work... I guess leopard will load on either PPC or Intel, but found the original grey mac osx discs for a different intel imac and it's loading fine. I like my iPhone... hate macs tho. ] How do I close this thread?

The retail copy was introduced before intel macs. Since all intel macs shipped with 10.4 (until 10.5) and included the correct disc, there was no reason for Apple to sell a retail copy as there was no market for it.
