I decided to buy my wife a late 2011 13" MBA. To save a few hundred bucks, I went the Craigslist route. I figured, "Hey, I'm good with computers..." So we pick it up from this girl who very obviously was ready to get rid if it, possibly an ex-boyfriends... (or girlfriends, no judgement) She had what I'm pretty positive were illegal copies of CS5, Microsoft Office, and Windows 7 running in bootcamp, and as she was ready to get rid of it she didn't wipe anything. I decided I wanted my wife to have a clean experience, so I attempted to wipe it myself. I launched the disk utility after rebooting with cmd+r and did exactly what I remember doing when I wiped my 2008 MBP running lion. First, I erased the bootcamp partition, then I erased the other two hard drives. Now, when I try to launch Lion installer, it acts like its installing for about 20 minutes, then I get the missing folder icon, the one With the circle and the line running through it. I've tried to see if there's anyway I can recover the install image, but when I looked for it, terminal said all of my disks were empty. How badly did I screw this thing up. I've also got a early 2011 MBP, is there any way to use it to hand over a fresh lion installer to the Air? I've already set up a Genius Bar Appointment for Monday, but I'd rather be able to fix it myself. Little help?
