Hi all, So i tried to install Vista on my new 2012 13' macbook air, but failed. I manually created a partition from disk utility and then tried to install directly onto the partition but it didn't work. Once i realized i was going to have to buy windows 7, i went back to disk utility and deleted the partition i created. When i resized my "Macintosh HD" partition, i am only getting a HD size of 119 gigs instead of 121 gigs. Since HD space is at such a premium, i believe i need to format the HD and reinstall Lion on to it. I don't really have anything installed aside from Aperture and Diablo III, so i don't mind doing this as i only got the machine over the weekend. So what is the best way to do this? Should i erase the HD from disk utility? If so how should i go about doing that? Any suggestions would be great. Thanks all!
