eXtern OS is available to you for free. However if you would like to help keep the servers running and help the developers, you can support me here.
If your computer has a resolution less than 1366×768 you will not have a good experience. If you ignore this warning, keep that in mind when testing. Please read the minimum requirements on the home page. Thanks.
If you live in an area where Google services are blocked/not allowed such as China, we recommend you to use this link

You have 2 options, to run it off a DVD or a USB. The advantage of a USB is that you can enable something called persistence. This allows eXtern OS to save changes across reboots when you run it on any computer using that USB. You now also have the ability to install eXtern OS alongside your current Operating System.
Run from USB for Linux Users
Download any bootable USB creator, one that has been tested to work that comes with a lot of Distros is “Startup Disk Creator”. If you do not have it you can install it on debian systems (i.e Ubuntu) using this command:
sudo apt-get install usb-creator-gtk
Also UNetbootin works fine!
