a quick run down on the situation: my GF bought a new hard drive a few months ago and the person that installed it did not make it the master hard drive. so the operating system and some of her files are on the old HD. her old her drive is only 20 gigs, and the amount of data i have saved on the new HD is well over that. my question: i cannot burn all of the files that are on the new HD to cd and then erase them from the hard drive because that would take too much time. and i also cannot move all the files on the new HD back to the old HD because it does not have enough storage. if i create a partition on the new HD and move all of the files onto that partition, can i install windows onto the empty part of the new HD without reformatting the whole HD and losing all of the data i just moved?
