similar setup--found that the HD graphics driver that is on the MB Express Installer disk (if you don't use the disk or this driver on the disk, windows update will try to install the same driver for you if you do not de-select it) doesn't seem to work--causes a black screen during boot due to no video signal. The generic driver windows setup installs works at high resolution but will install at poor resolution--so you have to adjust it. Haven't found a better solution for myself yet. System seems to think it has a VGA card. Found a lot of people posting the same problem and no real solutions yet.
