[ubuntu] Can't find hard drive for installation?

view story

http://ubuntuforums.org – Trouble finding a hard drive to install Ubuntu 12.04 on. As you can see, the 3.74 GB drive is the only one that is showing up. It seems that this is the USB that I am running Ubuntu from, and not an actual drive from the computer. Same thing happens when I try to install Ubuntu. The USB (with no free space) is the only drive that shows up. It seems that there should be an internal hard drive, but I don't know why it's not being recognized? This is a Gateway netbook that previously had Windows XP on it. If Win XP is causing the computer's harddrive to be hidden from gparted, how do I show i (Hardware)
