After helping a guy in another thread, I figured I should finally take the plunge and get OS X back onto my PB G4. I lent my Leopard disk to a friend in the States and will probably not be seeing it back any time soon, thankfully I made a backup of the disk (using dd before I sent it. I don't have any dual-layer DVDs lying around and would prefer to use a USB drive instead, but am having problems getting a bootable drive.

I tried a straight up dd, but it won't boot, I guess because it was taken from a DVD. Is there anything else I need to consider now that I'm not working with the traditional DOS MBR? This method works fine with all Linux images. The ISO format is ISO 9660.

tl;dr How to get Leopard ISO onto USB drive. Have Linux and Windows machines available.

If you made the backup on a windows or Linux machine, you're screwed buddy. Sorry.

OS X installers have all sorts of trickery to hide stuff on those OSes. Your best bet? Hit the Internet looking for a copy.

If you're going to pirate it, I don't want to hear about it. But it's an option. I'm going to stop talking now before I get into trouble.

Thanks for the suggestions. Well I've got some disks on order, so if all else fails I'll just burn it and use the optical drive.
