Just upgraded to 5.0. Upgrade went smoothly, but as soon as I tried starting my XP Pro VM it would blue screen. I get the following: IRQL_NOT_LESS_OR_EQUALL and the error code 0x000000000A (not sure if i have the exact number of 0's) but you get the idea. Booting in any safe mode still produces the error. The fixes listed in the support area do not seem to apply to this error. Does anyone have an idea of what is going on?
