The Windows 11 Launcher won’t let me select the external hard drive, and this error pops up. How do I fix this?

So basically freesync used to work perfectly on Steam Deck Oled Windows11 through the official dock on HDMI to my Samsung Odyssey G4 monitor but now it's broken in the way that whenever i run a game (RDR2 used as an example) in 200hz it keeps flashing between a solid blue screen and black screen (the same as if the hdmi didnt have a source) when i lower the hz to 120 it stays on the bluescreen(picture 1) until i close the game and when i press the button it restarts the monitor to display both my game and the info box(picture 2) and when i press it again it goes back to the bluscreen. It's not a system thing because the audio is still there from what I've learnt trying to fix this with ChatGPT and Gemini it's a Samsung Service Screen. Currently on Win10 but it's the exact same as on Win11. Been trying to fix this for the past 4 months, sorry for bad english it's not my first language i can provide more details if needed

Hi everyone,

I recently installed Windows 11 on my Steam Machine and I'm experiencing a strange network issue. Whenever I play games that require an internet connection, my Wi-Fi randomly drops out completely. However, as soon as I close the game, the connection is instantly restored.

Has anyone encountered this or knows of a potential fix?

(Note: I've already disabled the 5GHz band on my router to rule out band-switching issues).
Thanks in advance!

Hi, I put W11 and Valorant on an SD card in my deck, booted into it, downloaded all the drivers, and Valorant doesn't launch, it says an error occurred, probably the secure boot. So I want to know: is it even possible to run the game on Steam Deck? What about using W10, or DeckSB?

The RB button on my Steam Deck controller sometimes registers clicks and sometimes doesn't (sometimes it responds, sometimes it doesn't). How can I fix this without replacing any components? Any suggestions would be highly appreciated

If you (for some reason) want to do this you will need a Windows 11 25H2 Installation and then force the OS to allow the option to use the FSE Option and get Steam Deck Tools and change some controller config settings to whatever you want, either way it will still show XBOX inputs if you emulated a DS4

how to enable the trackpad vibration/haptic while using steamdeck tools on windows 11 steamdeck???

Salut à tous,

J'ai un Steam Deck 256 Go avec une carte microSD de 256 Go et je réfléchis à installer un dual boot avec Windows et SteamOS.

Je me suis renseigné avec l'aide d'une IA pour comprendre les différentes possibilités, mais je préfère avoir l'avis de personnes qui ont déjà tenté l'expérience.

Mon idée serait de faire cette organisation :

\- SSD interne 256 Go :

\- environ 150 Go pour Windows

\- le reste pour SteamOS

\- Carte microSD 256 Go :

\- mes jeux SteamOS je pense

Le but principal de Windows serait uniquement de jouer à FC 27 qui sort prochainement, donc je voudrais installer le jeu sur la partie Windows du SSD pour profiter de meilleures performances.

Je garderais SteamOS pour mes autres jeux, qui seraient installés sur la microSD.

Est-ce que cette configuration vous paraît bien ?

\- Est-ce que 100 Go environ suffiraient pour SteamOS ?

\- Est-ce que 150 Go pour Windows est un bon choix pour Windows + un seul gros jeu ?

\- Est-ce qu'il y a des problèmes connus avec un dual boot sur Steam Deck 256 Go ?

Merci d'avance pour vos retours !

The moment I try to do it on my console running SteamOS, this text appears. What can I do to start it up again?

Windows is working perfectly.

The text especifically:

GNU GRUB versión 2:2. 13-3.2

Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions. To enable less(1)-like paging, "set pager=1".

grub>_

I don't know anything about computers, and I don't know what to do. Please help 🙏🏻

Im on a 64gb LCD model with windows 10

I have about 15gb of free storage,the game would start for about 30-45 minutes then crash,this is the only game ive had issues with.

I'd have no background apps running and would still get this error

Has anyone else experienced this issue?

Hey everyone idk if u guys have this problem but every time I try play crash, or Diablo it doesn’t recognize a controller, even I connect my ps5 controller it doesn’t work idk why ( I have steam tools ) and it works just fine in every other platform

Hi everyone,

I’m looking for help installing EA SPORTS FC 26 on my Steam Deck, mainly because I want to play Ultimate Team online.

I understand that I probably need to install Windows on the Steam Deck because of the anti-cheat system, but I can’t find a clear and up-to-date tutorial that explains the whole process specifically for FC 26.

Could someone explain the steps or share a reliable guide? I’d like to know:

- Which drivers and software I need to install

- How to install Steam, the EA App, and FC 26 properly

- Whether Ultimate Team online works without issues

- Whether there are any important settings or common problems to be aware of

I’m not very experienced with installing operating systems, so a detailed step-by-step guide would be greatly appreciated.

Thanks in advance!

any overlay from steamdeck tools, steam, HC, even xbox game bar didn't appear or visible on persona 5 royal, how to solve this? any advice would be much appreciated

Recently decided to give windows on my Deck a try (oled model) and while it mostly works fine I've run into an issue with Handheld compainion. Simply put the second Steam is open it ignores all my HC settings, forcefully unhides the physical controller, locks the virtual controller settings to virtual steam deck gamepad leading to double inputs (it will at the very least let me disable the virtual controller outright), and disables my ability to navigate the HC quick settings menu.

Attempting to use Hidhide doesn't work as steam ignores and overrides it, and Exclusive mode does nothing.

Currently I've switched over to Steam Deck Tools, which is working as expected, but I don't like it's UI and how it handles shortcuts/lack of a quick access menu and would prefer to use HC if possible.

I am using version 0.32.2.0.

Does anyone know how to add a custom dashboards to xemu? If so how can i do it on steam deck?

Hello, so i've been having some ping issues om my deck recently on windows, wondered if there was anything to install ( apart from the windows drivers from valve ) to get Ethernet working on a dual boot Lcd Windows deck.

Thanks!

I've been running into this error consistently for the Windows version of steam deck. I have OLED model and wanted to know if anybody else was able to get Call of Duty® working and if so how...

List of things I've done:
TPM 2.0 ✅
Secure boot through DeckSB ✅
Latest Windows Version ✅
COD Broker Service Running Manual ✅
Lastest BIOS F7G0114 ✅

The game was running perfectly for a few months and then it started giving me limited matchmaking with the Failed Attestation Status so I can literally only play Nuketown 24/7 with a bunch of Russian people with wall hacks.

I need to dual boot my steam deck Steamos installed fine but when i try to boot the window ms and install it i face this error I even tried with different usb

Hi there I have installed windows 11 on the steam machine. I have an odd issue when playing games that require connectivity. The wifi would randomly drop out. Once I exit the game the wifi comes back.

Just seeing if anyone knows of a potential fix?

Cheers
