While I was looking for something that is interesting about Ubuntu, I found this cool application that will install Ubuntu directly from your Windows. No need to do partitioning, no need to smash your head to do the Ubuntu setup, the only thing that you need is, Wubi.
Wubi is a Ubuntu installer that will install Ubuntu from your Windows. Which means, you can install Ubuntu exactly like you install games or other applications in Windows. And if you don’t like it, you can uninstall it from Add/Remove Programs.
