I tried it piggy backed off the CD-ROM. I have tried a hand full of drives, and i tried 2 in my G3 iMac and they worked fine. My 10.4 disk is kinda scratched so i will try and make an image from it and burn a fresh copy, try a brand new HDD and if i can a new DVD rom.
I have a 10.3 disk, that booted but its meant for a G5 iMac. I could get to the disk utility but it got stuck in an infinite spiny thing while trying to "prepare to erase"
