How Can You Install Windows on a Steam Deck?

Installing Windows on the Steam Deck opens up a world of possibilities beyond its native SteamOS environment, allowing users to access a broader range of software, games, and customization options. Whether you’re looking to run Windows-exclusive titles, use productivity applications, or simply want the familiarity of a traditional desktop experience, installing Windows can transform your handheld device into a versatile powerhouse. This process, while approachable, requires some preparation and understanding to ensure a smooth transition.

The Steam Deck, designed primarily for gaming on SteamOS, supports Windows installation thanks to its PC-like hardware architecture. However, shifting from the default Linux-based system to Windows involves careful steps such as creating bootable media, managing device drivers, and configuring system settings to optimize performance. While the idea might seem daunting to some, many users have successfully navigated the process, unlocking new functionalities and enhancing their overall experience.

In the following sections, we will explore the essentials of installing Windows on your Steam Deck, covering the necessary tools, precautions, and tips to help you get started confidently. Whether you’re a tech enthusiast or a casual user, this guide aims to equip you with the knowledge to make an informed decision and enjoy the best of both worlds on your handheld gaming device.

Preparing the Steam Deck for Windows Installation

Before initiating the Windows installation on your Steam Deck, several preparatory steps are essential to ensure a smooth process. First, you must create a bootable Windows installation USB drive. This requires a USB flash drive with at least 8GB of storage and a separate computer to download the Windows ISO and create the bootable media using tools like Rufus or the Windows Media Creation Tool.

Next, backing up your Steam Deck data is crucial, as installing Windows will overwrite existing data and potentially remove SteamOS. You can use external storage or cloud backup solutions to safeguard your files.

It is also recommended to update the Steam Deck firmware to the latest version. This ensures compatibility and may provide improved hardware support for Windows.

Finally, disable SteamOS’s Fast Boot and Secure Boot options in the BIOS/UEFI settings. Access the BIOS by holding the Volume Down button while powering on the device, then navigate to the boot or security settings to adjust these options.

Installing Windows on the Steam Deck

Once your bootable USB drive is ready and the Steam Deck is prepared, proceed with the installation:

Insert the bootable USB into the Steam Deck using a USB-C hub or adapter.
Power on the device while holding the Volume Down button to enter the boot menu.
Select the USB drive as the boot device.
The Windows installer will launch; follow the on-screen instructions to select language, time, and keyboard preferences.
When prompted for installation type, choose “Custom: Install Windows only.”
Select the Steam Deck’s internal drive. It is advisable to delete existing partitions to ensure a clean installation.
Proceed with the installation; the device will reboot multiple times during this process.

Keep the device connected to power throughout to avoid interruptions.

Installing Drivers and Configuring Windows

After Windows installation, it is vital to install appropriate drivers to enable full hardware functionality, including the touchscreen, audio, Wi-Fi, Bluetooth, and GPU.

Valve provides a dedicated Windows Driver package for the Steam Deck available on their official website. Download and install this package immediately after the first boot into Windows.

Key steps for driver installation and configuration:

Connect to the internet via Ethernet or USB tethering if Wi-Fi drivers are not yet installed.
