UPDATE: Apr 25 2024 - this guide also works for SteamOS 3.5.19

UPDATE Nov 16: SteamOS 3.5.5 has been released to stable! This contains BIOS 118 and it can mess up with the EFI entries making SteamOS unable to boot.

** This video was originally created using SteamOS 3.5 Preview. SteamOS 3.5 Preview contains BIOS 116 update.

** Then on October 06, Valve has released SteamOS 3.4.11.


I've created a quick video how to fix it -

Fix for SteamOS 3.5.19 Update Not Booting

1. Hold volup + power then select boot from file, then select steamos, then steamcl.efi

2. Wait a few seconds until it goes to game mode

3. Go to desktop mode to recreate the SteamOS entry.

4. Open konsole terminal and type the command

sudo efibootmgr -c -d /dev/nvme0n1 -p 1 -L "SteamOS" -l "\EFI\steamos\steamcl.efi"

5. Reboot once completed.

The konsole command both options are L.
First is uppercase L, the second is lowercase L

If you are using my clover script for dual boot then it is way easier - just follow step1 manually boot to SteamOS and the script will fix the dual boot automatically.
