This is going to get accomplished with the help of a very easy to use installer that will allow you to have Debian running on your machine in a blink of an eye.

Debian GNU/Linux is a free operating system, developed by more than a thousand volunteers from all over the world who collaborate via the Internet. Debian's dedication to Free Software, its non-profit nature, and its open development model make it unique among GNU/Linux distributions

!! WARNING !! The Debian-Installer Loader will be installed over your Windows OS so make sure you want to switch to Linux before running it, because you will not be able to rescue your Windows installation after installing Debian using this software !!
