adding hard drives

Ok, so, currently i have a mac pro, and i have a 250gb hard drive with a windows partition on it, formatted in Fat32, so about 35 gb for that partition. I am adding two 400 gb hd's, one will be my main hd with OS X only, the other will be a back up strictly for OS X; i will then make the current 250gb for windows only. So, i would like to know if there is a way to get the windows onto the 250 without reinstalling the OS. The only thing i could think of, is if i clone the 250 including the windows partition onto a 400 (would that even work?) then reformat the 250 for windows only, copy the windows partion from the 400 over to the 250 and then clear out the windows partition on the 400, would anything like that work, or am i just going to have to re-install windows? any other solutions i am up for.

 

cool, i will look into that,
