I have power mac g5 and i have two hard drives. I installed mac os 10.5 on it first then did all the updates for the mac os 10.5. Then i installed debain sid 12. After reboot i can't boot into mac os 10.5. I Just get linux to boot on to grub. How do i get it to show mac os and linux so i can boot into linux or mac os? Thank you for the help.
