This version allows you to run linux in a window on a ‘Windows’ machine. It’s kind of like a virtual PC in concept.
I’ve not played with it yet but I believe that it’s easy to install. It’s a big download but comes with a stack of software packages installed.
There is a Wiki and a forum for support (from my limited experience the community support for Linux is usually excellent).
The website still looks a little ‘technical’ but try not to let that put you off. It’s easy enough once you get going.
