I just bought a 320 gb seagate HD and I've installed it into my MacBook pro 13" from last June. I formatted it as Mac OSX Extended (journaled) and I have my old MacBook hard drive in an external enclosure. How do I set up my new harddrive from my old one? It's not time machine or anything just the hard drive that was in my MacBook previous to the new 320. EDIT: UPDATE ON ISSUE; I let my start up disc restore my new hard drive to my old hard drive and it finished so I shut it all off, took out the disc and unplugged the external (old hard drive). I start it back up it sits at grey screen apple logo pops up and then it goes to a dark grey screen that tells me I need to restart and turn it back on and there's a list of other languages it tells me to do that. So I did so and it goes and does the same thing. Right now I'm booting from the external as the boot drive and the internal is just acting as an external. I looked in finder and it seems to be copied correctly and all I just don't know why it won't boot. I might have to try those other suggestions.
