Can I remove a second install of Mac OS X? I had to get the logic board and HDD replaced on my Unibody MBP, before I sent it back to Apple, I took a DMG copy of my hard drive thinking I could just remount it once I got my MBP back.

When I got it back it had a blank Snow Leopard install, when I tried to restore the backup that I took, I had to create a new partition and mount the DMG to that. So now I've got 2 Mac OS X installs on the MBP.

I changed the default boot partition to my old install so I can use the MBP as it was but I want to put it back to its default behaviour.

Can I just use Time Machine to backup my old Mac OS X install and restore that on the blank Mac OS X install I got when Apple sent my MBP back?

What happens to the second partition I created? Can that be removed?
