Download and burn, slowly, the latest stable version of gparted live cd iso, (url below). You could use the gparted version in the menu of the live cd install disk but just in case it is bad, which is a distinct possibility, it would be nice to have a means of verification. Use the gparted live cd to make your partitions.
I would suggest pre-making your partitions and then doing the install. When you get to the partitioning part select "manual" and assign the pre-made partitions to the mount points.http://download.linux-live-cd.org/Super ... sgd/cdrom/
I am assuming you are making a standard install, not an install through Windows. If you are trying to install through Windows, the above info does not apply to you. I can't help you with that situation.
