Virtualization
I had heard about something called Virtualization: to run multiple Operating Systems simultaneously. I had nothing else to do, so decided to give this a shot.
First, as always I went over to Wikipedia and here is what I found.
I decided to try VMware, downloaded a trial version and then I was raring to go.
The host operating system was Windows XP. I installed Windows 98 SE as guest operating system and here I was! Running two Operating Systems side-by-side! It looked way too cool!
Then I installed Ubuntu. So now I am running 3 Operating Systems: at once. 
The good thing about virtualization is that the guest operating systems are isolated from the host operating system. The guest OS can be used for software testing and to run software that you doubt about. (The best example: software cracks)

i had once tried with 3 OS on harddisk..win 98, win xp and fedora core 1..and it was really big pain 2 uninstall all of them lol..VMWare is cool but it eats lots of RAM..

@Arun: Yup. RAM problem is there, but look on the positive side. You can experiment with other Operating Systems without the worry of messing up your Windows partition. And this is recommended for software testing. At least I use it for that purpose.
Teen: Keep it up.
