SteamDeck_rEFInd

Please feel free to donate and support me at the following link. Donations are not required, nor are they expected. I will continue to work on this repository and potential future variations, with or without donations.

Updated installation method is SteamOS 3.5 compatible. An optional background randomizer feature has been added.

This is a simple rEFInd install script for the Steam Deck meant to provide easy dual boot setup when using both SteamOS and Windows on the internal NVMe. Since the initial version of this script, optional support has been added for Windows from the SD card, Batocera from the SD card and an example boot stanza for Ubuntu (or other Ubuntu based flavors / distros). The options really are pretty limitless, but require some understanding and manual edits to the refind.conf file.

The GUI is available and is the recommended installation method

If you want to try out the GUI, perform these steps.

💾 [as of 29/08/2024 rEFInd GUI has a bug for Windows on go (Windows installation on SD card). After installing GUI please consider following instructions from "Windows from Micro SD card instructions" below if you have your windows installed on micro SD card.] 💾

cd $HOME && rm -rf $HOME/SteamDeck_rEFInd/ && git clone https://github.com/jlobue10/SteamDeck_rEFInd && cd SteamDeck_rEFInd && chmod +x install-GUI.sh && ./install-GUI.sh

The GUI files will be created in the /home/deck/.local/SteamDeck_rEFInd/GUI/ folder, including a desktop shortcut. Please give me feedback and enjoy!

Prerequisites and Setup (no GUI method)

This installation script assumes that there are valid EFI boot entries for both Windows and SteamOS on the esp partition. For SteamOS there should be a valid EFI boot file located at /esp/efi/steamos/steamcl.efi . For Windows, there should be a valid EFI boot file located at /esp/efi/Microsoft/Boot/bootmgfw.efi . If you are missing either of these, or they do not function as intended, do not proceed with the installation script unless you know how to edit the boot entries in the refind.conf file to point to your correct EFI boot files for the OSes. You can confirm this by pressing Volume Up and Power buttons, then going to boot from file and selecting these manually. They should boot correctly into their respective OSes, otherwise do not proceed with the installation script (or proceed at your own risk).

It should be noted that if you follow the typical setup method for dual boot, those EFI files should be in the appropriate place and valid (accurate assumption in most cases).

The icons can be replaced with any 128x128 icons that a user desires. Please just make sure to update the refind.conf file for the correct icon names, if deviating from what's provided here. The background can also be any 1,280 x 800 properly formatted picture. Same as with the icons, if you plan to use a different background, make sure you update the applicable line(s) in refind.conf for your background image. PNG format seems to work best for the backgrounds, with the fewest compatability issues.

I recommend making any changes to the icons or background picture and refind.conf file before running the installation script.

Installation instructions (no GUI method)

If you've cloned my repository in the past and want to make sure that you have the latest updates, from the SteamDeck_rEFInd folder on a command line run git status. If you see that any files are missing or that any files need updates, you can either delete the directory and re-clone, or run git reset --hard origin/main. You can double check afterwards with another git status, which should say "up to date" if nothing is missing or changed.

From a SteamOS command line in desktop mode, run these commands one after the other.

git clone https://github.com/jlobue10/SteamDeck_rEFInd/
cd SteamDeck_rEFInd
chmod +x SteamDeck_rEFInd_install.sh
./SteamDeck_rEFInd_install.sh

Alternatively, if the pacman repositories experience an issue during the pacman based installation, you can run these last two lines instead, for a pacman free installation method. This method uses rEFInd downloaded from Sourceforge.

chmod +x refind_install_no_pacman.sh
./refind_install_no_pacman.sh

If all went well, you should have rEFInd setup with SteamOS as the default loading OS. Feel free to adjust the timeout from 5 seconds to whatever desired value in the refind.conf file. This is how long you will have to choose your OS before the default OS loads. A value of -1 for the timeout will automatically boot the default OS unless a button or trackpad is interacted with in the pre-boot sequence, after powering on. Select the desired OS using the right trackpad and the R2 (trigger) button, or with the D-Pad and A button.

For additional configuration options, please refer to the rEFInd official documentation. My supplied config file uses manual OS boot stanzas on purpose to control the icon order from left to right. This feature is something that I plan to take advantage of in the config file generation (and installation) GUI that I am developing. Please feel free to deviate from this and use rEFInd's ability to detect EFI files and OSes to boot, if you want. The config file has a lot of potential options that I encourage people to explore.

Disable Windows EFI entry or run the Windows' side script "Dual Boot Fix"

❗This honestly should be in a bold flashing neon light, as it is one of the most commonly missed issues. This step is still required for SteamOS 3.4+. Unfortunately, this still requires booting from the SteamOS recovery USB or another live Linux distro. This step would prevent windows to boot automatically after system restart, making it possible to access rEFInd dual boot menu on each restart of the system.

--Removing EFI entry from boot order using SteamOS recovery USB Steps (while system is booted into SteamOS recovery USB):

1. Open "Konsole"
2. type: efibootmgr
## Take note of the Windows EFI four digit number and replace the XXXX in the following command with that number.
3. type: sudo efibootmgr -b XXXX -A

--Alternatively it is possible to run Windows' side script (especially if first solution doesn't work for some reason, giving Boot entry not found error problem)

Steps (While system is booted into Windows):

1. Download Dual Boot Fix
2. Unzip downloaded archive
3. Run "Setup_rEFInd_Windows_RunAsAdmin" as an administrator
4. Let the process finish, console will close itself automatically

Dual boot fix link <===

Instead of deleting EFI entry as in first solution, this script creates scheduled task which runs whenever windows is accessed and will move rEFInd dual boot menu to the very top of the boot list, on top of windows boot manager. There's a video from Deck Wizard on how to run this script if you want to have visual instruction. (Time code 17:57)

Restoring missing EFI entries

This functionality has been automated with the systemd service, if the systemd service is enabled.

If the EFI entries for SteamOS and rEFInd have been deleted by a BIOS update, then just manually boot into SteamOS from the 'Boot from file' option in BIOS.

Note about systemd service

The GUI now has buttons to easily enable or disable the systemd service ('Sysd On' and 'Sysd Off').

Due to the nature of SteamOS' partition structure (redundant rootfs-A and rootfs-B partitions), it may be necessary to occasionally double check whether the systemd service is still active and functioning properly. These redundant partitions are likely used for branch changes and/ or updates (or in case of failure of one or the other... not entirely sure). A useful command to check whether the systemd service is functioning properly is this.

sudo systemctl status bootnext-refind.service

If the status is anything other than active and enabled, it's possible that you may need to recopy the systemd service to /etc/systemd/system/bootnext-refind.service with sudo permissions. As this is a rare issue, I don't feel it's necessary to check for and automate this. If you had to recopy the systemd service onto the other redundant (now active root) partition, then you will also want to run this to start the service and enable it for future boots into SteamOS.

sudo systemctl enable --now bootnext-refind.service

Necessary steps for reinstalling Windows

You will need to re-enable the Windows EFI boot entry to allow the Windows installation process to complete unhindered. Replace YYYY in the following command with the Windows EFI entry number to re-enable the Windows EFI boot entry. The script will disable it again later, if it is re-ran after successful installation. Please be aware that this disabling step requires SteamOS recovery image for SteamOS 3.4+ (at least for now).

sudo efibootmgr -b YYYY -a

Additional Windows considerations (corrupted display on boot into Windows)

There is a newer, better fix than what was previously documented that actually prevents this issue in the first place. You can run a specific bcdedit command from either a command prompt or powershell (both require as administrator). This command should be run as soon as possible on a new Windows installation if a user plans to use rEFInd.

Command prompt command:

bcdedit.exe -set {globalsettings} highestmode on

Powershell command:

bcdedit /set "{globalsettings}" highestmode on

💾Windows from Micro SD card instructions

This is automated in the GUI. Just make sure the Windows SD card is inserted for the 'Create Config' step and install the config afterwards. The manual steps below will still also work, but they are less convenient than the GUI method. [as for 29/08/2024 rEFInd GUI has a bug which prevents UUID volume value pull to refind.conf file located in /esp folder. This means that steps below are important to do for windows on go (windows on SD card) users at this time being. Not following these instructions will lead to "Invalid loader file! Error: Not found while loading bootmgfw.efi" error.]

refind.conf file has a manual config for a SD card Windows boot option. To access refind.conf simply follow these steps:

1. Open "Kolsole"
2. type: sudo nano /esp/efi/refind/rEFInd.conf
##Now you must be able to edit configuration file.
##Following instructions will provide info about configs that located at the very bottom of this file.

Make sure to disable the other "Windows" boot option by adding a disabled line in that "Windows" config. it must look like that:

menuentry "Windows" {
	icon /EFI/refind/icons/os_win11.png
	loader /EFI/Microsoft/Boot/bootmgfw.efi
	graphics on
	disabled

We need to make 2 edits to the "Windows SD card" config to make the micro SD card Windows boot properly from rEFInd: UUID volume value and removing "disabled" line from wingows SD card configuration.

1. First, we need to find out the Micro SD card's EFI system partition UUID. I decided to use KDE Partition Manager to find out this information for Micro SD card. See the following picture for the highlighted partition UUID.

Copy UUID you found and replace the volume REPLACE_THIS_WITH_SD_CARD_EFI_PARTITION_UUID line with your appropriate UUID. For my example, this line becomes volume 2FB0D40F-C809-4C67-8B50-136D93B78543 .

2. Then it is important to delete the disabled line at the end of the Windows SD card config.

Press CTRL + O and follow the instructions at the bottom to save the file. The Micro SD card Windows rEFInd entry should now be active (after these 2 steps) and should look like that:

menuentry "Windows SD card" {
    icon /EFI/refind/icons/os_win11.png
    volume 2FB0D40F-C809-4C67-8B50-136D93B78543
    loader /EFI/Microsoft/Boot/bootmgfw.efi
    graphics on

In my brief test case, I found it necessary to press a key to avoid disk checking upon boot. I'm not sure if this is common for Windows from the SD card, as this is not my normal setup. It's just something to be aware of. If you miss pressing this interrupt key, the screen may look corrupted until the disk check completes and Windows continues to boot.

Disabling and/ or uninstalling rEFInd

If you've tried rEFInd and decide you just don't want to use it any more, you can delete the rEFInd EFI entry with this command (replace XXXX with rEFInd EFI entry number).

sudo efibootmgr -b XXXX -B

To uninstall the package and files that came with the pacman installed rEFInd package run.

sudo steamos-readonly disable
# These next two commands may not be necessary, but they don't hurt anything either
sudo pacman-key --init
sudo pacman-key --populate archlinux
# The following command performs the pacman refind package removal
sudo pacman -R --noconfirm refind
sudo steamos-readonly enable

Once refind is uninstalled, the GUI can be removed with the following commands:

rm -rf ~/SteamDeck_rEFInd
rm -rf ~/.SteamDeck_rEFInd
rm -f ~/Desktop/refind_GUI.desktop

The non-pacman installation script files would be a little bit more complicated to delete, but not too difficult if somebody insists on steps for it. Since those files only take up a very small amount of space on the 5GB root partition (not taking up any space for games on the /home partition), I am not going to go over that in more detail here.

To remove the rEFInd directory from the /esp partition (be forewarned that making a mistake here and deleting the wrong files or folders on the /esp partition could render your Steam Deck unbootable and in need of the recovery image. Consider this a fair warning and me taking no responsibility for user error here.) run this command.

sudo rm -rf /esp/efi/refind/

Future plans

I have an unreleased repo meant for laptops and desktops with generic Linux and Windows rEFind dual boot support (with support for secure boot). I may release this at some point, but there's no ETA. This is mostly coded up here but it needs some attention for finishing touches. Useful pull and merge requests would be appreciated.
