OK, figured this out. After going to back into the windows installer and trying to load the drivers for my ssd I noticed that my c drive is actually showing up as the d drive in the windows install and the c drive was showing as a system reserved/recovery drive. A little random...
Also worth noting that you can't actually boot win7 pro from a vhd, what itIT pro would want to do that? Its only available for ultimate and enterprise versions.
