ur question is very confusing, that disk is a boot disk for booting into windows desktop, what I think ur trying t say is moving the partition on C drive, Vista & Wind 7, I think have that build in, us folks down below, have t a find programs that can do it. I had the same problem, I have a sony vaio xp home e, & for some stupid reason, gave a 120 gig HD w 20 on c & 100 on d, & windows OS takes up 4 gig's & the updates take 4 gig's r higher, so u end up w 14 gig's, & stupid me started installing all kinds of programs & music & video's, after a month I was running low on room on c, they didn't tell me t install all on d, & everything would have been fine, but it wasn't t be, there r programs that move r re size partitions but they cost the big bucks, Partition Magic is the best, however I did find one for free. called Easeus Partition Master 6.1.1 Home Edition for free & there is a free back-up program that u can download also, when u go t move the partition, do it on D first, select the D drive & w the handle arrows on the partition bar line move it back 20 gig's, select C drive & move that bar up t meet ur 20 gig mark, then at the top right of the Program, there a check mark for archive r go hit that & it will re-size it, hope that helps>:) Voila
