    How can I make one after I’ve already installed Lion and restarted?

      um, check your applications folder, if its not still there then you need to download it again and go through the process… until i find a smarter way :D

        You can reinstall it by going to the app store.  Hold Option while you click the “purchased” tab at the top and an “install” button should reappear next to OSX Lion. That will re-download lion to the applications folder and from there you can follow the above directions.

      You have to download it again if you already installed it. The install process wipes it. Just got this info from the regional mac rep.
