Just to add something i had trouble with. After installing windows, to get back to SteamOS, you need to get to bios and select bootmanager and select SteamOS. If steamOS doesnt appear in the list than, in the BIOS, select boot from file and select esp/efi/steamos/steamcl.efi. and steamOS will start. Thx for the tutorial.

This is my second time using this tutorial (First time after upgrading the SSD) and I would like to offer a huge thank you for this... Kudos

Took me a while but thanks to you i now have set it up properly. This is the best guide i have found so far!

YET ANOTHER GREAT VIDEO, it wasnt long at all cause you showed everything we needed for a smooth process! Thank you so much for the instructions, worked like a charm.

Oh man this video deserves 1MM views, holy crap, what a great tutorial. Very well structured, with pointers to other videos where more details are needed for some of these pieces. Super helpful!

I actually stumbled on your video when I was looking for ways to dual boot windows I tried using various methods but to no avail or make the process seem to much of a chore. Despite the video being super long but it was worth it every step of the way is easy to do and guess what everything works as shown for that you get a sub.

Dude you explained things that I already know and make me see them in a different angle. Thank you, today I learned a couple of things

Thank you very very much : THIS helps a lot to bring Windows to the new SSD instead of using the slowdown Windows-SD . Glad you are here !

Best video I've seen. I had watched a few prior to getting an upgraded HD, glad I found this when looking for the most recent videos on the subject. You went very in depth, thank you.

This was very easy to follow. Only gripe was you didn't show how to reboot back to steamOS without Clover (You can do so by pressing vol. down and power as usual and then selecting the steamOS drive).

Great tutorials. While I’m sure I just need to play around with them, the hot keys section was confusing due to the speed you were going. I still need to do the FPS etc part but I did everything else and I’m so happy. Thank you!

Great tutorial, made this process work flawlessly in 2024! Long, but it covers everything in perfect detail!

Followed this guide from start to finish and it was so helpful. Thank you Overkill! Subscribed and liked.

Of course I liked and subscribed. I don't know if it's the music, the tutorial itself or a combination of both...but this video made a brotha cry. You're the man bro. Much respect to you.

I appreciate this very much. I got everything set up. Now im just trying to figure out how the hell to change the boot theme background. Thank you!

The best out there, hands down. GREAT detail!!! Thanks!!!

Thank you, my steam deck arrived 3 days ago and now i switched to revi OS and part with handheld companion setup helped me a lot

Did step by step ,everything working for me , thanks man for the turtorial !! :)

THIS is how instructional videos should be done. Professional in every sense of the word!

Thank you bro this is the BEST guide out there for dual boot steam deck setup.

Great tutorial still today. Everything went smoothly and thank you much!

Nevermind, I got it working. Damn as easy at it looks it took me almost 4 hours to finish this since I fiddled with mine after work. Working great now! Thanks a lot man.

Great video, guys. Glad Mute was mentioned in the video. Helped me out a lot in discord. I totally get the questions about how it worked before but not now kind of things. It really kept me from tinkering up till now. I didn't feel like I was a bother at all when yall helped me out. Thanks a lot.

Subscribed and I look forward to following this tutorial. So simple and well made.

honestly I thought this was a really big channel when I seen this but I just noticed. you deserve way more than 5.29k subs

What a superb guide, you got yourself a subscriber!😄

If anybody has the issue of "windows could not prepare the computer to boot". When you partition the STEAM DECK SSD, make sure to make the partitioned amount NTFS otherwise it will not work. It cannot be unallocated or any other format. I spent 2 hours finding this out so hopefully it helps somebody

Just came here from Reddit and appreciate the help man New sub for sure 👊🏻

Overkill knocks it out of the park with this tut, absolutely brilliant. Thanks for putting the effort into this. I, as well as alot of others genuinely appreciate your effort bro. Very well done! now, my only question is, whats that live desktop your rocking? haha! cheers.

Starting to watch these tutorials before I preorder the new oled deck next week!!!

Thank you for the video ! This is really helpful for someone like me who is not tech savvy 🙏🏻

very helpful followed every step right works perfectly good job man

Very informative video! I will try this out sometime

Thank you this made my steam deck a lot more user friendly

This guide is really really good man thanks

Thanks for the video! And thanks for the clover recommendation, I was testing refind before I installed windows, and it wasn't working. With clover, I got the dual boot interface, even with just steamos 😊

Got my new steam deck 512 model, all set up to Dual Boot menu unreal highly appreciated 👌 but confusing but I managed 😅

Thank you for making this video it helped me a lot. I got everything to work. To make Bluetooth work I had to create a folder called "REALTEK" in the Program Files folder under Local Disk (C:) -> Drag the whole Bluetooth driver installer folder into desktop -> open it -> right click the installer then "Run as Administrator" (Works right after without restarting). For the Handheld Companion app get the latest version online instead of the link provided in the description. Using the old version of the app then updating manually within the app breaks the app (The app won't open after the update for some reason).

Thank you, I appreciate the hard work. I just subscribed

strategic placement of ad 🔥

Thank you, works like a charm :D

One thing to note is, if you make a MicroSD bootable in Linux, you may have trouble in Windows, where the drive may not even appear with drive letter or in partitioning tools. You can fix this by using Ext2Fsd to recognize the drive, give it a letter, and format it for Windows.

Nice content man. I learned a lot. Thanks!

Very comprehensive... Thank you.

Thank you so much for your video - it helped greatly!

Thanks Bro. Helped me run this flawlessly

Dope Stuff man!! So many opportunities in handheld hybrid gaming..

I love you for this! thanks so much for sharing!

Nice video man! VEry well explained. One thing to mention is that it can take up 30 minutes to partition the drive. While so the progress bar will stay at 0% (atleast it did for me). And went all the way up to 100% at once when it was finished. I can imagine people not being patient and thinking what the hell is going wrong. But just be patient it is running in the background.

Hi, I'd like to say a massive thank you for this complete tutorial. Very helpful to me, and awesome with the tweaks.

I watched your previous guide. Very detailed and answered all of the questions that popped into my head. Btw would you consider doing a gameplay test for Gundam Battle Operation 2 on the steam deck with windows? It's a recent port from Playstation to PC. The game is free to play on steam. I searched everywhere but I can't find anyone showing anything like this.

I was having an issue where it said windows would not create a partition, when I could get it to work it would give me the windows cannot reboot this device error. To fix this I had to select MBP instead of GPT partition in rufus

okay so i dont understand after 3:38 when i boot with the usb drive it promps me to instal windows it doesnt take me to the screen you were on to partition the sd card

Great tutorial! I had issues with Rufus and Windows 11. I got the 'Windows Could Not Prepare the Computer to Boot' error. I fixed this by using the creation tool to prepare the USB directly.

Superb, Thank you very much

Thank you for this great tutorial!

Hello. On my Boot Manager, I have 2 SteamOS. How do I delete one of them? They both use the same directory so I'm afraid to use the Konsole comm. to delete it.

So I'm planning on doing this to add a small build of batocera to my steam deck, not windows. Same order of events. One question though. The steam recovery image is necessary to be able to access and resize the internal ssd and add the new partition that will eventually hold the new OS, right? You can't just add a partition to the internal ssd while runnig steam os. I think that's right.

gracias por el tutorial, me llevo medio dia pero lo logre . tienes un seguidor mas

great video. thank you so much!!

Getting a steam deck soon this is gonna be the first thing i will do

My steamdeck froze after opening the file from the flas drive. Its stuck on the steam logo and the loading wheel at the bottom hasn't moved. I'm afraid to turn it off and on again.

I had followed a different guide to dualboot windows on steam deck and after 3 days I finally managed to do the whole process only to be hugely dissappinted by the performance I was getting on the games I could not play on steam OS, not even mentioning the fact I could not get the controllers to work outside of games downloaded on steam, but now that I watched your video I'll be going back to windows for a final try on playing fortnite and COD on my steam deck, hopefully with HC and removing bloatware, performance and controller issues will be reduced enogh for those games to be playable.

This took atleast 4 hours to do I had to redo the recovery drive step twice because for some reason it wasn’t saving the changes to the disk partition then it took forever to setup handheld companion but in the end I got it to work, also if you need a cd key, I got a working one at gamers outlet for like 5 bucks *make sure it matches the version you set up*

Very helpful thank you!! I get an error when opening handheld companion saying your pc doesn't have an app that can open this link. I tried searching for xbox game bar in the store but there's only an xbox app. I updated it and followed your tutorial as if it was the game bar but I don't think it's the same.

Well done guide!

Thank you so much for making this video. It helped me a ton! I was able to get everything installed and loaded up game pass through the Xbox app but I keep getting this error. I've went through deleting the Xbox app resetting the store and verifying login information matches. Can't get past it though. Have you seen this before? clip license device id does not match

I had refind dual boot before but ended up having issues. I've fully got windows on it now but I may do this instead once I get a 2tb

subscribed, thanks

Such a good guide!

Great tutorial. I do have a question about the partition part. I only have windeck on my current drive, so I need to partion to add steam OS. Can I do this with your steps? Seems it would be a little different in my case. Also would I lose everything currently on my SSD if I do?

Hey, what format are you using your micro sd card to run the games? Also does windows automatically put the shader cache to the ssd ? Or the to the micro sd card? Thank you

Bro u saved my life I wasted so many hrs with another guy on KZfaq bro method is solid is even faster than this one but he never updated on the garbled screen nd u even included all that extra stuff drivers nd apps other KZfaqr is just straight installing windows and that’s it that shit all laggy af nd for a guy a like me nd more beginner out there u the guy thanks bro keep doin yo thang fr

When i Write the last command they said to me « rEFInd is Not détected Proceeding with the cliver install » help pls

Hello! I have installed Windows 10 Enterprise on my brand new SSD First. Will I still be able to dual boot to SteamOS using this trick?

hi, for a new ssd i need to install SteamOS firts, so i can go to the menu and do the partition of the ssd? i didn't understan that part of the video. Or by choosing the recovery iso of sd card it will install steamos and do the partition at same time?

finaly usefull video thanks so much

Damn dude, great guide and well narrated! You should do voice acting, you have a very unique voice.

I tried doing this but it says i dont habe enoigj room for in my esp partition???

I did not know steam OS had a partition editor in its desktop mode. I had used Gparted for the drive resize, lol.

Can you still dual boot if you format the sd card linux format?

Why is the OLED video driver called Aerith Sephiroth Windows driver?

so when i have the thumb drive connected to the deck in the beginning i boot with that drive and it isnt loading into the os, it just shows the steam logo and infinitely loads, is there any way to fix this?

| need help on something, please answer. when I install windows and go to boot manager to go back to steam os, then go back to boot manager to try to go back to windows it doesn't show the boot windows option. Just clover and steam os. I reinstalled windows like three times already and it keeps disappearing from boot manager. And when I try to use clover menu to load into windows it just shows a bunch of blue lines and I can't see nothing. Please tell me what do I do

hi! i have done everything and it works! i also partitioned my SD card using ur other video. ty so much for making this. when i start the device clover has 3 options: steamOS, Windows Internal SSD (where windows is), and windows external ssd/microSD. any idea how to hide the microSD option? also it looks like it is shuffling thru different themes, i don’t really want that lol i imagine the options are explained in the github but i figured i would leave the questions here and try to answer them myself later

if for some reason i decided to remove windows and return to having only steam os, can i merge the partition made for windows back to the one with the steam os?

Thanks for the guide, very straight forward easy guide and took me about an hour to do everything. Question though, how did you map the steam button to start menu? There's no Windows Start Menu option under hotkey? Also, not sure if you played roblox, but roblox won't detect any of my controls if I disable Desktop layout unless I launch steam. If I enable Desktop layout, it acts like a mouse and it's very hard to play with the cursor. Do you maybe know any way to fix this? I tried DS4Wireless, but DS4 doesn't detect the controller at all.

only issue I had was being unable to click "install" for the audio drivers. When i right click it doesnt give the option. anyone have any solutions

got problem with rufus making windows 11.the format option only shows ntfs with default size 4096 bytes default. is it okay or how can i change it like you did with LARGE FAT32 with 32 kilobytes. sorry, im new to these stuffs.

Hi, do I have to reimage before doing this or can I just resize my ssd even if it’s half full already ?

Hey sorry I'm a total noob to everything to do with this! So when you're saying download Rufus and the steam drivers for windows etc, do I download all of them onto the thumbdrive, and run all the exe.s etc for them too on the thumb drive? Essentially everything that says 'all downloads used' I do onto the thumb drive first? Thank you!

So, I can't seem to extract the .img file from the .bz2 file to get the .img file into Rufus. Do I need to extract it, or can I just use the .bz2 file?

hello i have a question. i just buy second hand steamdeck with dualboot manager. i have no problem going into windows 11, but when i was going into boot manager and choosing steamos it gave error like sending me to gnu grub version 2.06 and it said "minimal BASH-like line editing is supported. For the first word,tab list possible command completion. anywhere else TAB lists possible device or file completion" what should i do? the previous owner said i should have just go into steamos withour problem. is it because they log out from their account?

sorry i have a question... so when i partition the ssd a part holds SteamOS and the other Windows, but is it possible to intstall games there too or games can be installed only on the SD card? ty for the help :)

Is it possible to keep all the content on my steam deck and partition the 64 GB?

So if I followed this method and didn’t want windows anymore would I just boot into steamos recovery mode and delete the windows partition and add it back to the steam os one?

Thank you for the great video. My Steamdeck arrives tomorrow. Along with a 1TB SSD to replace the factory 64 GB. I also have the 1 TB ScanDisk extreme. Would you recommend making a bigger windows partition to install windows games on the SSD or a small partition to utilize the microSD for Windows game storage? I would image if you use the microSD for Windows games, you format (NTFS) the entire microSD?

I just ordered my sad upgrade (1TB) for my 64gb steam deck. Can I add the dual boot while I switch my ssd or do I need to change it, add steamos. Then restart and readd dual boot?

hello very good video im just confused on how to get back into steam os when i go into boot manger it dose not show up
