I bought a few new MacBook Airs in July 2013 and I'm trying to install and Windows 7 image. When I boot into WinPE, I lose functionality of the keyboard. Also, the Macbook Air doesn't recognize any drive partitions I have connected to to the laptop via USB. Any ideas what might be causing this?
Note - I have other Macbook Airs I use that were purchased in 2011 and 2012 and I don't have any problems using the same WinPE cd to boot.
