I've just purchased a new MacBook Air that has Mountain Lion preinstalled on it. My MacBook Pro (Late 2008 model)'s hard drive died and I bought a new hard drive to replace it. I do not have a back up or anything, unfortunately, and the optical drive on the Pro is broken (I do not have my Snow Leopard installation DVD either). I'm assuming that since I bought Mountain Lion OSX as part of my MacBook Air, I should be able to use that same copy for my MacBook Pro. Is there any way to do this (I know I will have to make a bootable flash drive but the primary question is if I can somehow copy Mountain Lion from my Air onto my Pro).
