Steam Deck - Installing Clover Script for Dual Boot Between SteamOS and Windows (and other OSes too!)

About

A collection of tools that is packaged into an easy to use script that is streamlined and tested to work with the Steam Deck running on SteamOS.

• The main program that does all the heavy lifting is Clover - a graphical boot manager / boot loader.
• Clover Toolbox is a shell script that offers a simple GUI to configure some aspects of Clover script.
• Custom systemd script that performs a sanity check whenever SteamOS starts up making sure that the dual boot is intact and repairs it automatically if needed.

What's New (as of October 25 2024)

1. Updated Clover EFI from 5159 to 5160.

Video Tutorial - How to Install Clover for Steam Deck dual boot

Click the image below for a video tutorial and to see the functionalities of the script!

Quick Install Steps - if you are in a hurry then this is what you need (but really you should read the rest of the README!)

Perform some Windows config first! Boot to Windows and open elevated command prompt -

1. bcdedit.exe -set {globalsettings} highestmode on

2. reg add "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation" /v RealTimeIsUniversal /d 1 /t REG_DWORD /f

Once done, boot to SteamOS to install Clover!

1. Boot into SteamOS, then go into Desktop Mode and open a konsole terminal.
   

2. Clone the github repo.
   

   cd ~/

   git clone https://github.com/ryanrudolfoba/SteamDeck-Clover-dualboot

   If it errors that folder already exists, delete the old folder first -
   

   rm -rf ~/SteamDeck-Clover-dualboot

   Then perform the clone again -
   

   git clone https://github.com/ryanrudolfoba/SteamDeck-Clover-dualboot

3. Execute the script!
   

   cd ~/SteamDeck-Clover-dualboot

   chmod +x install-Clover.sh

   ./install-Clover.sh

   
   

4. The script will check if sudo passwword is already set.
   a. If it is already set, enter the current sudo password and the script will continue.
   If wrong password is provided the script will exit immdediately. Re-run the script and enter the correct sudo password!
   
   

   b. If the sudo password is blank / not yet set by the end user, the script will prompt to setup the sudo password. Re-run the script to continue.
   
   

   c. Script will show a menu. Select which OS will be the default selected in the Clover GUI boot menu.
   
   

   d. Script will continue to run and perform sanity checks all throughout the install process.
   
   

5. Reboot the Steam Deck. Clover is installed and you should see a GUI to select which OS to boot from! Use the DPAD and press A to confirm your choice. You can also use the trackpad to control the mouse pointer and use the RIGHT SHOULDER BUTTON for LEFT-CLICK.
   
   

Why Use this Clover install script for dual boot?!?

1. Makes as little changes as possible to the SteamOS / Windows installation.
2. Makes dual boot with SteamOS / Windows easy with a nice GUI.
3. No extra config needed for Ventoy, Batocera, Kali, Ubuntu and Fedora. (if there are other OS you want to be added just let me know)
4. Automatically and easily re-create the dual boot entries if it gets broken by a BIOS / SteamOS / Windows update. No need to type manual commands!
5. Supports random themes (Mojave and Catalina bundled in the install script), add / remove themes, icons, background using Dolphin File Manager.

Using the Clover Install Script

Read this first - What does the script do?!?

1. The script copies files to the /esp/efi/clover location and manipulates the EFI boot entries.
2. Extra scripts are saved in ~/1Clover-tools which performs a sanity check on each reboot, and an uninstall script to reverse any changes made.
3. systemd service is created and also injected on the other rootfs.

Read this first - Prerequsities for SteamOS

1. No prior traces of rEFInd or scripts / systemd services related to rEFInd.
2. sudo password should already be set by the end user. If sudo password is not yet set, the script will ask to set it up.

Read this first - Prerequisites for Windows

VERY IMPORTANT - If you plan to use Windows installed on the sdcard, make sure that it is setup as GPT and Windows-to-Go in Rufus.

1. This applies to Windows installed on the internal SSD / external SSD / microSD.
   

2. No scripts / scheduled tasks related to rEFInd or EasyUEFI.
   

3. APU / GPU drivers has been installed and screen orientation set to Landscape.
   
   

4. This is VERY IMPORTANT! Do not skip this step. If you skip this step, the display will be garbled when Windows boots up!
   Open command prompt with admin privileges and enter the command -
   bcdedit.exe -set {globalsettings} highestmode on
   
   

5. This is IMPORTANT! Do not skip this step. If you skip this step, the time will be messed up!
   Open command prompt with admin privileges and enter the command -
   reg add "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation" /v RealTimeIsUniversal /d 1 /t REG_DWORD /f
   

Read this first - Uninstall Old Version of Clover Before Using this Script

1. If you are using an older version of my script, it is recommended to uninstall it first before installing the new one!
2. Open a konsole terminal and run the uninstall script -
cd ~/1Clover-tools
./uninstall-Clover.sh

Once you have read the above, perform the following steps to install Clover

1. Boot into SteamOS, then go into Desktop Mode and open a konsole terminal.
2. Clone the github repo.
cd ~/
git clone https://github.com/ryanrudolfoba/SteamDeck-Clover-dualboot

If it errors that folder already exists, delete the old folder first -
rm -rf ~/SteamDeck-Clover-dualboot

Then perform the clone again -
git clone https://github.com/ryanrudolfoba/SteamDeck-Clover-dualboot

3. Execute the script!
   cd ~/SteamDeck-Clover-dualboot
   chmod +x install-Clover.sh
   ./install-Clover.sh
   

   
   

4. The script will check if sudo passwword is already set.
   a. If it is already set, enter the current sudo password and the script will continue.
   If wrong password is provided the script will exit immdediately. Re-run the script and enter the correct sudo password!
   
   

   b. If the sudo password is blank / not yet set by the end user, the script will prompt to setup the sudo password. Re-run the script to continue.
   
   

   c. Script will show a menu. Select which OS will be the default selected in the Clover GUI boot menu.
   
   

   d. Script will continue to run and perform sanity checks all throughout the install process.

How to Add / Remove Themes

Read this first - ESP partition size

The esp partition is only 64MB in size. This is where SteamOS, Windows and Clover EFI entries are saved.
The free space on the esp partition is around ~25MB. Make sure the themes you download don't exceed this size!
You can have multiple themes installed and Clover will automatically pick a random theme on every reboot!

Read this first - custom icons

When adding your own theme, make sure to name your custom SteamOS and Batocera icons as follows -
os_steamos.icns
os_batocera.icns
This are just regular PNG files, but you have to rename them to have the icns file extension.
Sample icons are saved in custom\iconset folder. Thanks to WindowsOnDeck reddit members u/ch3vr0n5 and u/ChewyYui !!!

Steps to Add / Delete Themes

1. Boot into Desktop Mode and then open Dolphin File Manager.
2. Navigate to /esp on the lower left side. It will say "Could not enter folder /esp"

3. Right-click and select "Open as Root."
   
   

4. Enter the sudo password when prompted.
   

   
   

5. A new folder will appear for the esp partition.
   Take note of the free space located in the lower right side. On this example the free space is around 26MB.
   
   

6. Visit the Clover Themes github to download the themes. Make sure the themes you download doesn't exceed the free space of the esp partition from step5.
   

7. Navigate to efi > clover > themes. It will show a list of themes installed. By default it will show 3 - random, Catalina and Mojave.
   
   

8. Don't delete the random folder! It is needed so that when there are multiple themes installed, Clover will randomly pick a theme on every reboot.
   

9. Delete the themes you don't want and copy / paste new themes that you have downloaded.
   

10. Reboot and enjoy the new theme!
    

OPTIONAL - Scheduled Task for Windows. Use this only if you have Windows installed on microSD / external SSD and if Windows keeps hijacking the bootloader!

Use this only if you have Windows installed on microSD / external SSD and if Windows keeps hijacking the bootloader!

Known Issue

1. If Steam Deck is docked and connected a TV / display higher than 1080p (4K, 1440p), the GUI screen will be sideways. This is purely cosmetics and once an OS is selected it will boot in the correct orientation.

1080p TV
