Wubi is an unofficial Ubuntu installer for Windows users that will bring you into the Linux world with a single click. Wubi allows you to install and uninstall Ubuntu as any other application. If you heard about Linux and Ubuntu, if you wanted to try them but you were afraid, this is for you.
Wubi is Safe
It does not require you to modify the partitions of your PC, or to use a different boot loader.
Wubi is Simple
Just run the installer, no need to burn a CD.
Wubi is Discrete
Wubi keeps most of the files in one folder, and If you do not like, you can simply uninstall it.
Wubi is Free
Wubi (like Ubuntu) is free as in beer and as in freedom. You will get this part later on, the important thing now is that it cost absolutely nothing, it is their gift to you…
