Can someone please walk me through the process of booting my Leopard disc from one iMac G5 to another? It won't boot from USB so I am trying to do it by connecting a firewire cable between the two computers. For the record, I tried holding down the option key while starting up my computer (the Leopard disc being in the other computer) and selected Mac OS X and the clicked on the right arrow, but it still doesn't seem to boot from the disc. Am I doing something wrong? I have a 1.8GHz processor with over 1 G of RAM. It is one of the earlier G5 models with no iSight and without the Intell Processor.
