so here is my problem, i made my windows partition too small. i use it mainly for games and didn't fully realize the size of games these days. i decided to use a 500gb hd that regrettably is USB. i kept windows on my mac but moved steam and all the games onto the hd. now everything is slow to load (naturally) and it just isn't a great experience. what would i need to do to backup windows onto the hd, delete my partition, make a new bigger partition, then restore onto my mac? thanks much!
