In my quest to fix/backup my G4 iMac, I've loaded an install of OS X.3 onto my iPod. However, I can't seem to boot from the iPod correctly. What I am doing is using the Hardware test/system restore DVD to boot into the start-up disk selector. I enabled the iPod in disk mode so it could boot from it. When I select the iPod as the boot disk, it displays a circle with a cross through it similar to the icon on the iPod when it says "do not disconnect". I've verified that there is indeed a full copy of OS X on the iPod by connecting the iPod to my PC and viewing the files. What is the problem here?
