I've got this dual G5 powermac that I got off ebay for $240. it works just fine, has 10.4.11 on it. I have this backup of a leopard retail install that I later ended up breaking, couse i ran it over with an office chair (doh) anyway i figured i could just make a bootable USB and load it off there. guess not, apparently you cant do that on ppc macs. so I went on to make a bootable partition on my FW drive as I read this should work. but thats where it gets funny. if I on my MBP open the install i get the message "cannot install mac os x from this disc" I went ahead and tried anyway, but the g5 wouldn't recognise the fw drive as bootable. I then tried to make a bootable partition on the internal drive, but I get the same message.. any idea what I could do?
