this is a couple of years old mbp intel.. should be possible.
I had bootcamp, and I'm not sure exactly how i crashed the disk.. but something happened when i tried to use deamon tools to mount an image file residing on my mac partition (access through macdrive).. (I know.. bit experimental and risky..)
Anyway, Instead of trying to fix it, I decided to rescue what i could and do a complete reinstall of the machine.
Got parallels up, and looks impressive, but havent tested warband yet. I'll let you know when i'll be able to test it tomorrow.
cheers!
