vista opk issue

I am trying to refresh some restore images for windowss vista home premium
64bit. This is happening on several intel motherboard with g41 and g45
onboard video. Every time is reseal the machine in order to build a wim file
image, vista strips out the video drivers so that when its rebooted, the
video card is listed as a standard vga device. I though maybe it was they
intel's installer was loading the drivers but no pointing to the device infs
result in the same issue
