It goes without saying that everyone has a different taste when it comes to pretty much everything, so an operating system should be pretty much along those lines.

Some of us are more accustomed to working on Linux, some on Mac, while the wide majority prefer Microsoft’s Windows OS.

Even when it comes to the Steam Deck, which comes with its own Steam OS, some users might feel that installing Windows would be more appropriate for their needs.

Today, we’re going to show you how to dual boot Windows 10 or Windows 11 on our Steam Deck, just in case you decide that’s what you want to do.

 When it comes to Valve’s new gaming rig, we can also provide information on how to change Steam Deck’s resolution, or what are the best Steam Deck verified games.

Can I install Windows 11 on Steam Deck?

Yes, you can install Microsoft’s latest operating system on your brand new Steam Deck if you decide that the default OS isn’t for you.

In fact, we’ve shown you how to install Windows 11 on the Steam Deck back when we were still discussing compatibility between the handheld PC and operating system.

After a lot of time spent on the Trusted Compatibility Module (TPM) and with AMD to ensure Windows 11 compatibility, Valve is confident it has built a flawlessly Windows 11-compatible system.

Remember that, to install Windows 11 on your Steam Deck, you will need to download the OS and put it on a USB flash drive.

What OS does Steam Deck use?

Valve’s new device, the Steam Deck runs on a modified Arch Linux operating system that is called SteamOS v3.3.

The SteamOS had been initially developed for Steam devices using Debian Linux, but Valve stated that they wanted to use a rolling upgrade approach for the Deck’s system software.

That being said, remember that you can also install Windows on Steam Deck, as we are about to show you in today’s guide.

Can the Steam Deck emulate?

Even though it should come as no surprise, yes, Steam Deck can emulate a lot of consoles, arcade machines, and even MS-DOS games.

Also worth mentioning is the fact that there are plenty of legal emulators available to install and play your game backups.

Now, however, let’s take a look at how to perform this Windows on Steam Deck boot directly from your device’s USB.
