I have a powerbook g5 10.3.9. The CD drive is broke so i need to use my firewire external drive to install lepord. So i think i need to make my external drive bootable (without erasing the whole drive if possible). CCC or Superduper would not work on my OS. I kept getting errror messages like for CCC "no mountable file system" and panther doesnt meet Superduper requirements. Is there any other options for me?
