I bought a used Macbook Air with OS X 10.7 Lion installed but with no installation media. I purchased and upgraded to OS X 10.8 Mountain Lion. Now I want to go back to Lion, and I am happy to do a fresh install.
First, how do I get OS X 10.7 install media? I see "free downloads" on legit sites like Softpedia, but will it make me register and pay at install time? Or is there another/better way to get the media?
Would the Lion disk image be stored anywhere on the drive?
