The OS 10.4 would not install on my Mac G4 because it did not have a DVD drive. I connected a USB DVD drive and it reads the CD when the OS is up and running. When I click on the Install icon is says that the computer needs to reboot and then OS will continue installing. Nothing ever happens it just reboots and the OS loads. Could this be because I am using a USB DVD drive? Will a regular DVD drive work if I put one in the computer? If nothing else,can the OS installation DVD's be converted to CD's? Any help would be greatly appreciated.
