I am putting a new hd in my macbook. I have an external ( in enclousure) and have formated the drive to HFS+ ( mac extended journaled). I have a copy of Carbon Copy on the new hd and a copy of it in the internal. I would like to make a bootable copy onto the new drive and boot from there to test it. The question is, how do I make sure that the external drive is bootable? Does that just automatically happen when I make the clone?
