Dual-Boot Help

[nazgul42]

Ok... I have a Windows PC, and I read about Linux on it. It seemed interesting, so I inserted a hard drive I don't use and installed Ubuntu on that. I liked it, and now I want to set it up so that when I start my PC, I can choose either XP or Ubuntu, but I don't want to lose any of my Windows files. Does anyone know how to do this, or a good tutorial on it?

to have option at the time of boot, you should install grub or lilo boot loader.
u can install it from your linux CD.
