I decided to take the plunge today and load up Win 8 on my 2011 MBA (core2duo + 4gb ram). I did a clean install OVER Win 7 via the upgrade process since I had a Win 8 upgrade key. I g0t Win running and I cant load any of the new drives to install. I downloaded this: http://support.apple.com/kb/DL1638 I get this error when I run the setup: Boot Camp x64 is unsupported on this computer model What am I missing here??!!!
