How do I use GParted to partition my drive to install Ubuntu or any other OS?

http://askubuntu.com – After preparing my hard drive with GParted I was trying to see how to install Vista or Linux as an operating system. I really don't care if I have to erase my files. I just want my laptop back on an operating system. Also I put the Windows installation CD in the drive. It said the partition does not have enough volume to run Windows Vista? (HowTos)
