I believe there are a number or boot laoder programs that will do the job you want quite easily. Google boot loader windows, or boot menu and take yoour pick. This is probably a better notion than editing the current master boot record (MBR) on your hard disk but it could also be done by ading a line to that file (open the file in a text editor and) welll perhaps not for the inexperienced.
good luck
