Just a quick question here.. If I removed the boot drive from my macpro and, say, replaced it with the boot drive from a comparable computer running XP, and then turned it on, would I have a fully-functional windows PC? Also, if I wanted to migrate my OS and apps etc., would it be possible to simple remove the boot drive (with all my apps, etc.) from one macpro and put it onto the other? I don't see why this wouldn't be possible unless there are some issues with firmware/drivers... Any help would be appreciated!
