Wubi is an application which simplifies Ubuntu Linux installation on Windows partition. To Windows users, Wubi eliminates the hassle of having to repartition hard disk which carry the risk of loosing precious data.
Wubi does this by using a loopback device, creating a large file on a Windows partition and installing Ubuntu inside it. The best thing about Wubi is, it does not use virtual machine or any type of emulation. Thanks to Wubi, Ubuntu can be booted natively using Microsoft Windows boot loader.
When you are done experimenting with Ubuntu (who does?), or need to reclaim the hard disk space back, you can choose the uninstall button from the Windows Start Menu and everything will be removed, just as simple as that.
Wubi is one of the few application that made me wish that I have a Windows machine because I’m dying to try it out!
Wubi will be included with the upcoming Ubuntu 8.04 LTS (Hardy Heron) release, due in late April 2008.
