Be careful, installing Linux on a disk that already has data on it, might be dangerous if you don't know how, try Knoppix first before installing a distro on your hard disk, get familiar with it then chose a distro and install it.
Knoppix is a Linux which u can boot from CD or DVD, no installation required.
If you're using windows, you can download Virtual PC and install Linux on it, that way you won't need to have dual boot, and you can work in both OS at the same time.
