so im picking up a new 2tb external hard drive today for my new retina mbp ( see other thread https://forums.macrumors.com/showthread.php?p=15165007&posted=1#post15165007 ) obviously more space will make setting up bootcamp easier. im really a rookie though and have no clue what im doing lol. i plan on wanting to use windows vista and mainly use it to play games like battlefield. can someone help me out as to what i need to do with the drive and stuff? thanks
