So I've gone through hell and back since my new hard drive replacement arrived. I was trying to burn my Leopard image (.dmg file) from my MBP to my iMac G5 PowerPC. After many unsuccessful rounds of burning to DL DVDs and flash drives, I settled on making my iPod bootable and running it from there. So I'm excited and running my startup disk on my MBP as the iPod and I've connected my MBP to my iMac G5 PowerPC through firewire and enabled target mode. After booting into the iPod, it gave me the option to install to the new hard drive from the iMac G5 (which is currently connected to my MBP). I installed it through my MBP, and assumed it had installed to my G5. After going through the initial installation, I powered down both machines. When I powered up the G5, nothing. I KNOW that Leopard is installed on it, but it's not recognizing it for some reason. I can only boot from my MBP, it seems. It's not a compatibility issue with the Intel/PPC thing either. At least I doubt it. Where do I go from here? I've been working on this for at least 7 hours.
