Hi,
Thanks for the quick reply! I will try this as soon as I have the time.
The primary use of the PC is to use it as a HTPC but for some very rare occasions it would be nice to use it for gaming. The ATI card is far more suitable for gaming than the nVidia.
I assembled the PC a few months ago and at that time I still had an office room. Now the room will become a room for my son so the PC will have to move to the living room and I have to get a laptop. It would be a shame to have all the power of 4-core Intel i5-750 and not to be able to play some modern game every now and then.
But I agree, it doesn't make sense to have dual boot with yaVDR. That doesn't mean that I don't want to do it anyway.
