Why didn't he call AppleCare back? All he needed to do, with an Internet connection, was power on holding Command+R and the Mac does the rest (formats the new drive and creates a recovery partition, then, boots to it, and one of the options there is to restore the entire computer from a Time Machine backup). Done. He made this needlessly complicated, and really should have just called AppleCare back, as they could have easily walked him through these steps.
