Valve Releases SteamOS So Anyone Can Make A Steam Machine Now

• Windows: Use the Rufus utility. Select the SteamOS file and write it to your USB drive (this will format your USB drive).
• MacOS/ Linux: You can use Balena Etcher to write the SteamOS file to your USB drive.

When you boot into SteamOS for the first time, you’ll land on a desktop environment. Navigate to the “Re-image Device” option to start the installation, after which your machine will reboot. Note that you will need to disable Secure Boot to install SteamOS, which you’ll need to do in the BIOS. You can find where this is located in the documentation for your respective motherboard maker.

After those few steps you’ll be up and running SteamOS, giving you an identical living-room PC experience to the Steam Machine. Valve notes that discrete AMD GPU support is still technically in beta, so expect updates to come in thick and fast after the next few weeks. But given how much work has been done to prepare for the Steam Machine, never mind the years of development on the Steam Deck, you can probably rely on it being stable enough for daily use. It is, however, always a good idea to keep a backup of your current operating system (on an entirely different drive) in case you run into issues.

The Steam Machine goes on sale on June 30 exclusively through Steam, with Valve deploying a new method for orders that should hopefully avoid the same issues that plagued the launch of the Steam Controller.
