How to put an elephant in a match box ? You make it smaller !!!
First you'd have to make sure that your C: partition (with windows on it) and partitions before and after it needed for booting are all together much smaller than those 250GB drive, Than you need SW like Macruim Reflect free

All together it may be easier just to reinstall windows on new drive.
