Hey, I need some help. I have a Powermac G5 with Mac OS X 10.3 installed. I need to add a blank Partition that is 10GB. I need to do this to install Mac Os X Leopard. I had purchased a copy of the full retail Leopard install. The problem is that my mac won't read the DL DVD, I'm not sure why though it should read it. So I created a DMG from it on a friends mac and transfered it over with a flash drive. I would have booted from the flash drive but, only intel Macs can boot from a external storage device. So now I need to make a partition to restore the DMG to and boot off of it and install Leopard onto my other partition (the one with Panther on it and all my personal documents/files). But, I can't figure out how to make another partition without erasing all my data.
