If you still think installing Linux on PC is complicated, you may be wrong. Many people want to try Linux, but want to keep the existing Windows. Dual booting Windows XP and Linux is not that hard. Take a look of the steps in Linux-Talkz, you only need 4 steps to install 3 OSes on PC. That is, triple boot. From the source, it said,

1. Make a partition for Windows XP (SP2) which is about 2/3 size of the whole hard drive;
2. Install Windows XP into it;
3. Install Fedora 9 into the remaining space of the hard drive;
(* Now you can dual boot with both Windows XP and Fedora 8, grub loader *)
4. Now boot up from Windows XP, after it has loaded insert the Ubuntu 8.04 desktop installation CD, the installation prompt (GUI) will pop up. Follow the on-screen instruction to install the Ubuntu 8.04 into the machine within Windows environment (Thank Ubuntu for this genius design!), the triple boot PC is born!

Seems pretty easy.
