How to Install Windows on Steam Deck

0

Valves steam bridge runs SteamOS out of the box, which is based on Arch Linux. It allows for a streamlined, almost console-style experience that’s easily navigable with handheld controllers.

Despite Valve’s best efforts, not all games play properly on the Deck yet. Some games designed for Windows do not yet work well with Steam’s Proton compatibility layer for Linux. Additionally, SteamOS also does not support non-Steam games, such as those from the Epic Games Store.

But the Steam Deck is PC-based, which means there’s nothing stopping you from installing alternative operating systems. If you want to run your Steam games and also play those from other stores, Windows might be your best option. Plus, installing Windows means you won’t have any Proton compatibility issues for native Windows games. These games should be just as compatible as they are on the best gaming pc, but with the limited specs of the Steam Deck in mind. Additionally, using Windows means that if you’re an Xbox Game Pass subscriber, you’ll be able to play games from that service on the Steam Deck.

There are trade-offs, however. The operating system will be harder to navigate without a keyboard or mouse, and features like suspending games are built into SteamOS and won’t work on Windows.

You can find drivers for Windows on Steam Deck here. Since this update, there are drivers for GPU, Wi-Fi and Bluetooth, but not for audio. Speakers and 3.5mm headphone jack will not workbut you’ll be able to get sound through Bluetooth or USB Type-C speakers or headphones.

We will be running this tutorial with Windows 10. Windows 11 requires TPM firmware which, as of today, is not implemented in the Steam Deck BIOS. That will come in an upcoming update, Valve’s Lawrence Yang told me, and the steps for installing the new OS should be largely the same.

Before installing Windows 10, you can check our Windows benchmarks and impressions on Steam Deck to get an idea of ​​its performance.

We will detail two ways to run Windows on the Steam Deck. The first installs on the internal SSD, while the second runs Windows from a microSD card. The former is likely to be faster, but the latter is more reversible until Steam provides documentation on how to dual boot.

With all those caveats, here’s how to install Windows on a Steam Deck:

Method 1: Install Windows on Steam Deck SSD

Be careful doing this. Currently, Windows cannot be dual-booted, so it will take up your entire disk. To roll back, you will need the recovery image from Valve.

1. Create a Windows 10 or 11 installation drive.

To get started, you’ll need to create a Windows installer on a USB flash drive. To go here (opens in a new tab) to create one for the version of Windows you want to install. This is easier to do from a separate Windows PC. Follow the instructions to create the installation media.

2. With the power off, plug the USB drive into the Steam Deck.

If you have a USB Type-C flash drive, you can plug it directly into the port on the Steam Deck. Otherwise, you’ll need a USB-C hub to do so.

3. Hold the Volume Down button and turn on the system to enter the boot menu.

If you are using the Steam Deck controls, use the D-Pad to switch to “EFU USB Device”, then press A to select it.

4. The Steam Deck will start.

5. The Windows installer starts. Yes, it’s sideways.

If you’re using a USB-C hub, you can plug in a keyboard and mouse. Commands from the Steam Deck won’t do anything here. That being said, if you don’t have a keyboard and mouse, the touchscreen will still work.

6. Choose your language and click or tap “Next”.

7. Click or tap “Install Now”.

8. Activate Windows. If you have a product key, you will be prompted to enter it here. There’s a touchscreen keyboard if you need it. If you don’t have a key, choose “I don’t have a product key”.

9. Choose your version of Windowsthen click or tap “Next”.

Here we used Windows 10 Home.

ten. Accept the terms and conditions to continue.Check the box and click or tap “Next”. In other words, assuming you agree. If you don’t, shut down now and return to SteamOS.

11. Choose a custom installation of Windows. Upgrade installations only work on computers that already have a version of Windows.

12. Delete partitions to make room for Windows.

When you go to install Windows, you will notice that the SSD is divided into eight partitions and you cannot install Windows on any of them. You will need to remove partitions to install Windows. We deleted partition 8, which was the largest of them.

If you’re not comfortable with deleting partitions on your SSD, you might consider installing Windows on an SD card and booting from there, or even sticking with SteamOS. You can always go back to this point without deleting any data.

13. Select “Drive 0 Unalloced Space” and tap or click “Next”.

14. Windows will begin installing.

15. The Steam Deck will reset.

You may see the screen orientation change several times.

16. Follow the Windows installation process.The instructions are all on screen. You can again use a keyboard and mouse or the touch screen. Here, the up and down arrows on the D-Pad work, as does the A button, but the screen is still sideways.

If you want to connect to the Internet, you will need an Ethernet to USB cable. As of this writing, Windows on the Steam Deck does not have working Wi-Fi drivers.

17. The Windows desktop will appear. Note that it is always aside. We will correct this shortly.

Since the Windows drivers are not finalized, we received an error saying “Looking for display driver: Screen, resolution, performance, and battery life may be reduced until ‘a compatible driver has completed the installation’.

18. Go to Start > Settings > System > Display

19. Scroll down to view orientation and choose “Landscape” to orient the screen in the right direction.

Now you have installed Windows 10 on your Steam Deck. At the time of publication, there is still a lot to correct. The speakers don’t work, but you can get audio over Bluetooth or USB Type-C. To return to SteamOS, you will need to use a recovery image.

Another method: start Windows from a microSD card or a USB key

Note: We are using a microSD card here, but the steps should be the same for a USB flash drive.

To get started, you will need a Windows ISO. To go here (opens in a new tab) to download the media creator. This is easier to do from a separate Windows PC. Follow the instructions to create the ISO.

Next, you’ll need software to turn your microSD card into a bootable drive. We will use Rufuswhich is free, but if you know any other software, you can do it that way.

2. Open Rufus

3. Select your microSD card and Windows ISO

4. Under image optionchoose “Windows to Go”.

5. Sub partition schemeselect MBR. In advanced options, check “Use Rufus MBR with BIOS ID”

6. Click “Start”.Now you wait. It may take a bit.

7. Eject your SD card from your PC and place it in the Steam Deck

8. With the Steam Deck turned off, hold volume down and press the power button.

9. Select SD card in the boot manager. The D-Pad works to choose a player, and you can select it with the A button.

ten. Windows will begin to boot. (Yes, it will be on the side. This is normal.)

11 . Perform Windows Setup. You might want to use a keyboard and mouse here, although you can navigate everything with the touchscreen.

You will end up on the Windows desktop. It will always be aside.

Since the Windows drivers are not finalized, we received an error saying “Looking for display driver: Screen, resolution, performance, and battery life may be reduced until ‘a compatible driver has completed the installation’.

12. Go to Start > Settings > System > Display

(Image credit: Tom’s Hardware)

13 . Scroll down to view orientation and choose “Landscape” to orient the screen in the correct direction.

Since Windows is on the microSD card, when you restart your Steam Deck, you are back to Steam OS on the SSD. If you want to return to Windows, you will have to enter the boot manager (Volume down + Power) and select the SD card.

Updated March 10 with the fact that Steam has released Windows drivers for the Steam Deck.
