You should create a backup of your entire hard drive onto CD or DVD, if you have a burner of either type, then you can change the partitions around, using the fdisk command under DOS. Granted, this is techie stuff, and you should NOT use fdisk if you don't know what you're doing, so I would look into a commercial partition manager, put out by a reputable company. Some of them can change partitions without data loss, but not many. If you have any more questions about this, feel free to ask me, and I'll do some research into which are the better packages to buy.
