SteamOS has finally dropped in all its beta glory. While 300 lucky preview testers scored Steam hardware as well, most of us have to install it on our own machines if we want to try it out. Here’s how to do that.

Before we begin, there are some very important caveats:

  • This will wipe your machine. Due to the way Valve has distributed this image, you cannot partition a hard drive or dual boot it with your existing set up. This is a recovery image and your partition table will be wiped clean if you attempt to install it on the same hard drive. If you want to play around with it in a non-destructive manner, you can try it in a virtual machine. Once you have SteamOS installed, you can create a new Windows partition, but this will wipe your existing setup.
  • This may wipe your secondary hard drives, too. The basic method is not optimised for installing on systems with multiple drives. Depending on how your boot tables are set up, you might inadvertently lose data on your other drives as well. Keep safe and remove all hard drives except the one you want to install SteamOS on.
  • You’ll need an NVIDIA graphics card. Sorry AMD users. Support is reportedly coming in the future, but for now if you don’t have an NVIDIA graphics card, you’ll have to sit this one out.

What You’ll Need

Before you get started, here’s what you’ll need to download and/or collect:

There are two main ways to install SteamOS, and the method you choose will determine which download you need. The easiest method involves flashing a recovery disc image and that download is about 2.4GB (called “” at the link above). The slightly more complicated method which has all the fun expert buttons is about 960MB and labelled “”.

Method #1: The Easy Way

How to Install the SteamOS Beta on Your Computer

The simplest method to get SteamOS up and running is to install the recovery image. Again, as a reminder, this method will completely erase your entire hard drive regardless of partitioning. As long as you’re prepared for that, here’s what to do:

  1. Format the USB stick to FAT32. Name it “SYSRESTORE”.
  2. Unzip and place its contents on the USB drive.
  3. Boot your machine from the USB stick.
  4. While booting, select the UEFI entry from the boot menu.
  5. Select “Restore Entire Disk”.

This method will result in a complete, ready-to-use SteamOS installation being created on your machine. If you want to dual boot SteamOS with a Windows installation, you can set that up now. While the SteamOS release is based on Debian, our guide to dual booting Windows and Ubuntu can at least help point you in the right direction.

Method #2: The Advanced, Flexible Way

How to Install the SteamOS Beta on Your Computer

If you’re feeling more adventurous (or want to minimise how much you have to download directly from Steam), you can use the secondary method. There are two primary differences between this method and the previous one. For starters, the download is significantly smaller. Part of the reason for this is because once you install the OS, you still need to download Steam. What you’re installing is mostly just a customised version of Debian.

More importantly, this method has an Expert Install mode. You can use this method to tweak a few settings. That being said, if you’re not extremely experienced with Linux distributions and installs, you probably shouldn’t mess with this.

To install SteamOS via this method, follow these steps:

  1. Unzip the smaller, file to your USB stick.
  2. Boot your machine from the USB stick.
  3. Select the UEFI entry from the boot menu.
  4. Select “Automated Install”.
  5. Once the install is finished, boot into the OS. You will be faced with a login screen. There is a default account with both the username and password are “steam”. Log in with these credentials.
  6. Double-click the Steam icon on the desktop to download and install Steam.
  7. After this, you can log in to SteamOS via the login menu you used in step 5 (select “SteamOS” via the dropdown box) with the same credentials.

If you’d like to maintain the Debian installation and log in to SteamOS only when you need it, you can simply end here. However, if you’d like to commit all the way, follow Valve’s instructions here from step 8 in the final section onward to make the final customisation tweaks so that the partition is 100 per cent Steam.

Method #2.5: A Note On Virtualisation

How to Install the SteamOS Beta on Your Computer

OK, so you’ve come this far and you’re still not sure you want to take the plunge. That’s fair. SteamOS is still a beta and it requires a fairly big commitment. If you’d still like to give it a shot, you can install SteamOS in VirtualBox. If you don’t already have VirtualBox set up, our guide here will get you started.

The process for creating a virtualised SteamOS machine is a bit more complicated than the installs above, but this guide can walk you through the process fairly well. It builds on method #2 above, though instead of a USB installation, you’ll create an ISO out of the installer. Keep in mind, though, that running SteamOS inside a virtual machine will probably result in some pretty poor performance and almost certainly won’t be good for real gaming. This method is probably best for the idly curious who would just like to fiddle.


  • Well I won’t be able to try it until I build a new PC, only got 3 gigs of ram, 1.6 gb Celeron processor, and 80 gb hdd.

      • Yeah I know, I need a new PC badly. It did have 1GB of RAM, but I picked up two extra 1GB sticks of DDR2 RAM on clearance at my local Dick Smith for 99c each about 12 months ago.

        Been saying that I’ll build a monster gaming PC for the last few years now, hopefully next year I’ll finally do it.

        • it took me about a month’s worth of proper research (which parts to get, how to assemble, proper ways to overclock, etc) then a week to gather all the parts i’ve purchased, plus another 2 days to build and test thoroughly for stability..

          it was very worth it though, lasted me 4 years before i decided to upgrade!

    • Dude, that is basically the same as my win98 computer (which I still use). Save for the extra two gig of RAM you’ve got.

      Also funnily enough it’s been running since 2003. Well-picked, @choosk.

  • Awesome that they’ve brought out an OS, good on them.

    But NO way am installing this. Not taking a risk on a beta OS from a company that’s never made one before.

    But awesome that they’ve done it, and I expect big things in the future.

      • Exactly. It’s the same as buying a mobile phone with it’s own provider customised version of Android on it. I think this kind of opinion will be common though, especially from those who just play games. It’s also going to be Steam’s biggest challenge. Convincing people that it’s a better platform than the one they’ve been using for years that already works.

      • It’s more than that. It’s the future. If it goes well, in 5 yrs this will be on millions of PCs around the world. And that’s going to shake things up big time. No longer just 2 major players for OS’s.

        • Linux has been around for decades. It’s already on millions of computers around the world. What do you think Android is? Windows is still the dominate OS on desktops and their are some VERY good reason for that. Unless Valve single handedly fixes all the problems with Linux in the next 5 years. Nothing will really change. I’m glad Valve is doing this, but it seems more like a stunt to get game developers to support Linux rather then a valid attempt at competing with Windows.

          • Well I guess we’ll see. How many millions of PCs is steam on I wonder? That’s an incredibly strong advertising platform.

            Time will tell.

  • AMD really is shocking when it comes to Linux. I mean, sure, when people say gaming PC, ain’t nobody out there referring to Linux (yet, hopefully), but they could at least TRY to support the platform. At the moment it’s just a token “Yeah, we put out drivers for it. They don’t WORK but hey, they’re out there.”

  • x64 Processor – i7 4770k – Check
    4GB Ram – 16GB DDR3 – Check
    nVidia Graphics – GTX 680 – Check
    500GB HDD – WTF??? – 500GB required just for the OS??? – I run 2x 256GB SSD, why the heck would you need 500GB just for the OS requirements?

    • I don’t think it’s the OS itself that needs 500Gb.
      It may be a requirement for a used SteamOS, in case of a complete library downloaded.
