Hey @ED4T.. quick question, I'm on the 64 gig model of the steam deck, and no matter what I do, I don't have enough storage to install the apu driver. Any tips? Also amazing vid, only one that worked. Edit: I have a 256 gig sd card in it that's been split between the 2 OS.

[@jorisbonson386]

DON'T do it - wait for the official dual boot support from Valve, this is a band-aid which will be regularly broken by SteamOS updates.

[@leandromartins292]

Sir, you are completly right about the loading problems when installing and running Windows directly from a SD card. I had the same problems, but in-game, things taking too much time to load and when not gaming the disk usage (in the task manager) was always at 100%.

[@jonathansaraco]

For those who made the same mistake I did, if you get to the installing Windows stage and the installer exits saying "Windows cannot identify some drives on this device" it's because the micro SD card is still in the Steam Deck and Windows cannot identify those until you've installed drivers. Edit: The solution to this is you just remove the micro SD card. If you follow this tutorial there's nothing on the card required for Windows installation. So you remove it, install Windows, download the Steam Deck drivers for Windows which includes one for the SD card reader, then you can insert the micro SD and use it for SteamOS and/or Windows.

My guess is to install windows with a USB? Then, put ur SD card in with drivers that has both the drivers and windows installed? My issue is I have a sd card, I put windows on it and it asks for a product code.

When I do put on in, it says u need drivers

Hi I have 2 questions.

Also if I want to install the games on the ssd so I should skip the micro sd card step right ?

[@ED4T]

You dont need to re-image steam deck. just resize 1TB drive to windows. no need to delete any games from your Steam OS. yes if you dont want to use sd card for games you should skip the SD card step. you are correct.

[@waderobinson6672]

Once you have this set up how does storage work? Like can I add both steamos games and windows files to the same microsd? Also what happens to both platforms when I eject and change the sd?

[@ED4T]

yes the sd card is shared by both OS. you can add games from both os to the same sd card. if you eject the sdcard, everything store on the sdcard will be not accessible. the sd card is divided into 2 partitions one for steam os and one for windows. so they did not mess up with each.

you don't have to redo the entire process. you can just reinstall windows. after Windows is reinstalled. after you reinstalled Windows and now it boots directly to Windows instead of Clover! this is how to fix it: 1.

Are you talking about the dock stopped working in Steam OS or Both Steam os & Windows ?

[@eduardopinho2644]

@@ED4T thanks for the reply. It stopped working on both. Even turned off, it would not charge. It's a third party dock, but a good one (at least from what I read). It was working and after reimaging the deck and partitioning, at some point it just stopped, probably after using gParted - I did boot on that through the dock's usb. I read about people having that problem with any dock, including official one, and valve recommends putting the deck on shipping mode ("battery off" mode) and then back into plug, should work. I did that. And nothing on the dock. Tested another, though (genki covert dock), and it worked for both charging and HDMI out. So I guess the dock really died, not sure why. I even could ask for a refund, so all good I guess. Thanks again!

Hello, I have a problem - in the boot manager I ONLY have a partition for Windows, and there is no partition for Steam OS. you can see it normally in gparted, but not in the boot manager. I hope you can help me with this

[@ED4T]

try this: Start with Steam Deck off. Hold Volume + button and power. Choose "Boot from file". Select esp/efi/steamos/steamcl.efi. Wait until SteamOS boots (there will be a blank screen for some time, but Steam should start after that). Go to desktop mode. Open Konsole. EDIT: if you never used sudo then type passwd and press Enter. Then set up your password that you will have to use whenever you run sudo. Run following command: sudo efibootmgr -c -L "SteamOS" -l "\EFI\steamos\steamcl.efi" -d /dev/nvme0n1p1 This will add a boot menu option for SteamOS. EDIT: If you're typing the command by hand, 2 remarks: it is one line command (in mobile apps it might be seen as multiple lines) the third flag, between "SteamOS" and "\EFI... is a dash and lowercase L (it might look like number one or uppercase i)

yes same for win10

[@BeraEngMec297]

What is more reliable: Steam Deck tools or Handheld Companion?

[@ED4T]

steam deck tool.

[@BeraEngMec297]

@@ED4T Thanks!

[@john6268]

Very limited on space trying to get this to work. 20GB (with 27GB for SteamOS using 4GB swap and 7GB free) was not enough for the Windows partition even with Tiny11 (ran out space trying to do a Windows update). 24GB may have been enough, but that would have left 3GB for SteamOS or would have had to reduce swap back down to 1GB.

Can I do download to external hd, then move to my sd card on my steam deck? Also, Can I just pop out said sd card, and boot steam os again?

[@morfues3492]

Do I really need a mouse on partition part? Don't the touch screen work? I have no mouse nor dock station lol

the touch screen is not working with G-parted.

This might be a silly question but will this work on my oled 512gb version

[@ED4T]

yes it will, LCD and OLED steam deck use same setup process.

@@ED4Tthanks for the quick reply Also one more question if I may. My sd card is ext4 formatted on the steam deck. It does not show up on my pc is that still okay as I will be using a usb

[@quest2782]

would this work the same way with a tiny windows 10?

[@ED4T]

yes it will. this works with Windows 10 & Windows 11 any version.

I can’t get windows to boot from the partitioned I created. It boots from usb and doesn’t show me the windows setup screen. How can I fix this

Did you finish the windows installation ? Make sure your partition for windows is NTFS.

Hi, Can I make my micro SD as Windows 11 booter to install it in the internal space of the steam deck and then format the micro SD to install my games?

[@mterakedis]

That should be fine

[@peyton3333]

When I went to the boot menu to go back to steamIOS it was no longer there. Just the windows and the D and E drives

have you installed dualboot menu ?

[@YoruTap]

Can I use the same SD Card, for SteamOS and Windows at the same time?

[@ED4T]

yes, the SD card will be shared on Both Steam OS & Windows. One SD card to use for both operating system.

[@YoruTap]

@@ED4T but windows doesnt show the sd card in the explorer. I cannot read oder write things on it, besides on SteamOS.

[@ED4T]

Did you follow my step to 2 partitions on sd card ? You need create two partitions one for steam os and another for windows.

[@YoruTap]

@@ED4T yeah I see. I will do that. Thanks.

[@rolmilcent619]

wow so doing this i dont lose anything on my steam os or sd card?

[@ED4T]

yes, you are correct.

[@XxLSW21xX]

Quick question: When Windows first installed from me from the “This PC” screen I do not see my SD card like you did, any idea how to fix? I followed the guide exactly

[@ED4T]

Have you installed valves steam deck windows driver ? You need to install the sd card driver in order to see it in Windows.

[@johnmarkremotigue8985]

is it okay to use a 512gb SD card on a 64gb deck for dual boot?

yeah it doesnt matter, you can use 512gb or 1tb.

None, i dont so think so. cryoutlitles stuff are all belongs to linux partition.

Could you please help me with this? I installed windows on a new partition, but it had no storage whatsoever. so i removed the partitions of both steamos and windows, which merged them into one, and i formatted that to ntfs. i installed windows again, but it said i have 2 installations now and one goes to an error because it was removed. i want to go back to my default steamos but i have nothing now. what should i do? and how do i get rid of the broken boot loaders that dont work now (because they dont go anywhere)

[@ED4T]

Follow this guide and just re-image your steam os. It will get rid of everything include your windows partition. It will bring your SD back to its first day you bought it. How to Re-image Steam OS / Re-Install Steam OS / Unbrick Your Steam Deck kzbin.info/www/bejne/bKepnoKcabtphZY

[@HongSiewWai]

Hey guys, I just upgraded my deck to 2tb storage and planning to dual boot windows. Was wondering is it possible to shrink 2 extra partitions 1 is for windows (60GB) another 1 is for storage (1TB exFAT). The reason why is because exFAT can be shared for both Windows and SteamOS. Have anyone tried it before?

Hi, I have got to the end of the tutorial but when trying to reboot in to SteamOS, I only have the Windows option - I have rebooted into GParted and I can still see the ext4 Home is there, how do I go about rebooting in to Steam?

[@ED4T]

have you installed the Clover Duo boot menu? you need to install Clover to enable the dual boot option. otherwise, it will boot into Windows directly.

[@Taffam]

I haven't as I can't get into SteamOS!@@ED4T

[@Taffam]

Managed a workaround by booting in via file (hold volume up and power) which let me in to SteamOS, setup clover and all seems good now 👌

[@ED4T]

sorry for the late reply, try booting into G-parted again and see if the steam os partition still shows up in the GParted but if not, the only way you can fix this is to re-image your steam deck. I have a tutorial here for re-image the steam deck: kzbin.info/www/bejne/bKepnoKcabtphZY

Does windows run a lot faster on internal ssd over sd card?

[@ED4T]

i feel 2times faster on the 64 eMMC than SD Card.

[@twinturboaddict]

@ED4T so being that I replaced 64 with a 1tb ssd, should expect even better speeds? The time in takes to update games on windows from my SD is insane.

[@ED4T]

windows On sd card is totally useless. If you have 1tb ssd on deck I will definitely install it on SSD. The performance is lighting fast.
