Once you've done the above, read on to install Windows on Steam Deck.

How to Prepare the Steam Deck SD Card to Install Windows

How to Install Windows on Steam Deck - 3 Efficient Ways

There are three scenarios for installing Windows on Steam Deck:

Whichever option you choose, we'll provide you with the most comprehensive guidance possible. We recommend you choose the first option, where you can dual-boot Windows 11 and SteamOS by installing Windows externally on the microSD card.

Method 1. Install Windows on Steam Deck on SD Card

Installing Windows on the SD card may result in bad performance. But this is a good way to try out Windows on the Steam Deck before you decide to install it on your main system. In total, there are five stages as follows:

Stage 1. Download the Windows ISO File

On Microsoft's Windows installation media download page, select the Windows system you need and download the ISO files. The installation process is the same whether you choose Windows 11 or 10.

Download link:

Step 1. Next to the option to Create Windows 11 Installation Media, click the "Download Now" button.

Step 2. Download the media creation tool and accept the license terms.

Step 3. Select the "ISO File" option and choose where to save it.

Stage 2. Install Windows on the SD Card

Once you have downloaded the ISO file, you must use a specialized tool to help you install Windows. Rufus can help create a bootable USB flash or SD card drive.

Download link: https://rufus.ie/

Step 1. Download the Rufus executable and run it.

Step 2. With Rufus open, select the microSD card and then select Disk or ISO Image under the Boot Selection button. Select and open the Windows ISO file.

Step 6. Click OK to start the installation process.

Stage 3. Download the Steam Deck Driver on Windows

Since Windows lacks native drivers for Wi-Fi, audio, and other key parts of the Steam Deck, you'll need to install the Steam Deck drivers on Windows:

Step 1. Go to the Valve website and download all the drivers.

Step 2. Extract all the drivers after downloading them.

Step 8. On the desktop, change the screen orientation to landscape: Adjust it in Display Settings > Scale and Layout > Display Orientation.
