Hi,
A good partitioning program is GParted Live. The newest most stable release is gparted-live-0.4.5-2.iso which can be found at the following link for download:
http://sourceforge.net/project/showf...kage_id=271779
The nice thing too is, GParted is free and open source software available under the terms of the GNU General Public License!
But like simpswr said, your going to have to obtain the Installation CD if you want to install the O/S. If you obtain that CD it should have a built in partition/formatting tool.
Check this link out:
