Missing Space on HDD

Okay. So I got this computer to use for programming and older PC games, so my operating system of choice was XP. I went to install it, the install crashed and well now I am left with 1 partition (unallocated) that is 7.87 GB as appose to the 40 GB that were originally on the drive. I made a live CD of GParted (Seeing as I don't have an operating system) and it shows the one partition that I said about earlier. Any ideas? ): Thanks!

Nuke the whole thing see the result? dunno. Big magnet?
