i have never used a dual board before but i think i might have what you need...go to device manager, expand computer, go to the properties for whatever you have, acpi compliant pc, standard pc etc, go to the driver tab, choose update driver, and choose display a list of drivers or whatever it is when you get the chance, you might have to choose show all hardware of this device class...i hope this helped...damn, i wish i had a dual system...
