I've finally managed to install Win7 on my MBA and it is working great. One minor thing which im not sure I would call it a problem... The windows loading bar and animation on startup is not there. Just a black screen. It boots into windows fine, but for a bit there is nothing on the screen. I have already played around with the non GUI boot options under msconfig. Any other reasons? No major, but wanted to see if there was an easy fix or if others had experienced the same issue.
