One way is to download G-Parted and burn to cd .
then reboot to run the program. This is a linux based program and if you have any problems search for linux community
forms and they will help you gladly.
G-Parted is free and there are several other free programs to do the same thing.
Any one who needs help with this can email me at : wfs151@hotmail.com and I will get back to you as soon as possible
Hope this helps
