Everything you need to know before installing Steam OS
Valve recently released its Beta version of SteamOS, based on the Debian distro of Linux. Naturally, we were intrigued by its release and wanted to take the new OS for a test run. We’ve put together a guide on how to install the operating system, and also provide you with our hands-on impressions of Valve's software.
NOTE: Before beginning, we highly recommend that you back up everything on your system before attempting to install SteamOS, as the installer in this guide will erase your entire drive.
