Installing Windows on your Steam Deck allows you to access a familiar operating system and use the device as a work laptop or desktop replacement.
To install Windows on your Steam Deck, you need a USB flash drive or SD card, Ventoy software, a GParted ISO, and a Windows 11 ISO.
Follow our step-by-step guide to install Ventoy, partition your SSD, install Windows 11, and then install Windows drivers for proper functionality on your Steam Deck.
Do you want to have a familiar operating system or Game Pass on your Steam Deck? You can dual-boot SteamOS with Windows on the device. Here’s a thorough guide on installing Windows 11 on your Steam Deck.
Why You Should Install Windows on Your Steam Deck
Jhet Borja/MUO
If you’re someone who owns a PC, the chances are very high that you’re running Windows on it. Windows is familiar to many and is fairly easy to use.
While not having a mouse and keyboard on your Steam Deck will pose some navigation issues, having an operating system that’s familiar to you and that you know how to use might be worth that sacrifice.
Having Windows on your Steam Deck can also make it a work laptop or desktop replacement. You can easily use Photoshop, Microsoft Office apps, Lightroom, and all the usual suspects on Windows—so long as you’re willing to bring around a mouse and keyboard. Thankfully, there are plenty ofSteam Deck accessories that can make doing real work on it a breeze.
What You Need to Install Windows on Your Steam Deck
You only need a few things to install Windows on your Steam Deck, most of which are software. But you will need a few hardware accessories as well.
Hardware
For hardware, you really only need a USB flash drive and a USB-C hub to plug it into your Steam Deck. You can alsoinstall an SD card on your Steam Deck as long as it’s decently fast. A USB 3.0 or higher flash drive or a UHS-I or higher SD card would suffice, but we wouldn’t suggest anything slower.
We also highly suggest using a separate PC as we’ve done in this guide, but you can also use your Steam Deck and follow similar steps using the Linux version of Ventoy.
Ventoy
The first piece of software is Ventoy, a program that allows you to boot multiple ISOs from one external storage device without needing to format it to add a different ISO. This will avoid the back-and-forth formatting of the storage device used, making it easier to go back in case you make a mistake along the way.
Head toVentoy’s GitHub page and on the right side, click onReleases . Scroll down toAssets and click on the ZIP folder that says Windows on it. Extract the contents into a folder on your PC.
GParted is an ISO used to create partitions on your internal SSD on your Steam Deck. The new partition will be where you’ll place the Windows installation. To download it, head toGParted.org and click on theamd64.iso download file.
To put Windows onto your Steam Deck, you’ll of course need the installer. You can easily find this onMicrosoft’s Windows 11 page .
Head to theDownload Windows 11 Disk Image (ISO) option and on the dropdown menu, selectWindows 11 (multi-edition ISO) . Click onDownload , then select your language. It should then give you another download button to download the Windows ISO that is about 6GB to 7GB in size.
Windows Drivers for Steam Deck
Windows doesn’t support all the Steam Deck’s hardware straight from the get-go. Fortunately, Steam has provided Windows drivers so that your audio, Wi-Fi, Bluetooth, SD card reader, and APU are all working properly.
You can find and download the Windows drivers for your Steam Deck on theSteam Deck Windows Resources support page . Extract all of them into a single folder so that you can paste it onto your SD card or flash drive later.
How to Install Windows on Your Steam Deck
If you’ve got your flash drive or SD card ready with all the software downloaded, you can now start turning your Steam Deck into a Windows experience. In our case, we’ll be using an SD card so that we don’t need to deal with a USB hub or a dock.
1. Install Ventoy on Your Flash Drive or SD Card
To be able to run both the GParted and the Windows 11 ISOs from one SD card without needing to format it multiple times, you’ll need to use Ventoy. This will make things way more convenient.
To install Ventoy on your flash drive or SD card, you’ll want to plug it into your PC and open the Ventoy folder you extracted earlier. Then click onVentoy2Disk.exe .
You’ll then select the storage device you want to store Ventoy on. In our case, it’s the 32GB SD card. ClickInstall .
Now that Ventoy is installed, copy over GParted, the Windows 11 ISO, and a folder containing the Windows drivers for the Steam Deck. You can now insert the SD card into the Steam Deck.
Next, you’ll need to boot from the SD card or flash drive you’ve connected to the Steam Deck using the device’s boot manager.

To do this, shut down your Steam Deck first. Once it’s off, hold down the volume down button and power button until you hear a chime. Once you hear the chime, let go of the power button, but keep holding down the volume down button until the boot manager shows, like in the image below.
If you hold down the power button after the chime, you’ll most likely end up turning your Steam Deck off again.
Once you’re in the boot manager, select the SD card or flash drive. This should show Ventoy and both the Windows and GParted ISOs.
3. Use GParted to Partition Your Internal SSD
You’ll now need to partition your Steam Deck’s SSD. If you don’t, you most likely won’t be able to install Windows 11 on the /home partition, and you’ll also end up wiping SteamOS from your drive.
If you want just Windows on your Steam Deck, you can also use Ventoy to wipe all partitions and either leave the combined partition as unallocated or format it as NTFS. We don’t suggest this, however, as SteamOS really is the best way to experience the Steam Deck. It’s better to have the option to switch between the two than be stuck with just Windows.

On Ventoy, select GParted to run it. You can run it in normal mode, but if that doesn’t work, grub2 might do it.

Once GParted is open, you’ll be greeted with a few things before you can get to partitioning. Firstly, you’ll need to select the settings. Pick the first one—GParted Live (Default Settings) .
