Tex, the firewire drive has a disk image of the system. I need to create something to make it bootable.
Dan
A disk image (.dmg file) can never be bootable, under any circumstances.
In order to make your FireWire drive bootable, you need to do one of two things.
1. Use your computer's Install discs to install OS X on the drive, or
2. Use a program like the free Carbon copy Cloner to clone from your current internal drive to the external drive.
