thanks for the quick reply
so , if i could install windows 7 x64 and make use of all 4GB ram and video card availabe , i'll have to install the game in the virtual machine not the real one?
btw, will i be able to share folders with the original HD or even view the real HD?
Addendum:
ok, i tried that on xp
i used virtual pc, created a .vhd with windows xp, installed guest additions things, used easy bcd to add it to boot menu
and when i start to boot it from boot menu, it seems to boot with windows 7 ( the black screen with the text have the same style and font of windows 7 ) and it gives me an error,
i tried to start windows normally or last good configuration but it gave me that error
c:\windows\system32\halmacpi.dll is missing or corrupted
any suggestions?
