I'm trying to upgrade one of my PowerMac G5's to Leopard. No matter what I do, I cannot get it to boot to the install disc. When I put the DVD in, it's ejected after 5 seconds. I tried cloning the DVD onto a firewire drive, selecting it as the startup disk from System Preferences... this didn't work either. I even set up a netinstall image on my netboot server, which the boot loader would not recognize.
The boot loader itself is the older "Classic" type. When I have the firewire drive plugged in and hold down Option while booting, only the main HD shows up as a bootable option.
The firewire drive works on all other Macs I've used it on, as well as the DVD and netinstall image. There's another similar G5 that I've successfully installed it on, so I'm not sure what's going on here. I've tried resetting the boot loader by "command+option+o+f" then "reset-nvram" and "reset-all". These didn't help. I'm at loss for whatever else it could possibly be. Please help!!
