Linux is a great operating system -If you know how to use it-, and most people don't really want to be bothered installing, and whatnot, but it's really not hard to install, and if you use it often, it'll start being extremely easy to use.
The picture is my current desktop configuration, and I'll go through the programs I used to do that.
Step 1: What is this "Linux"?
These different Linux options are commonly called "distros", and some of the most popular are Ubuntu, Fedora, Debian, and Linux Mint.
These "distros" can be downloaded in .iso form, which I'll go into detail about later.
I'll be using Linux Mint for this instructable, so I'd recommend if you did too, but you're free to pick whichever you want.
(I'd recommend distrowatch.com for looking for a certain type of linux distro)
