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.

The latest stable SteamOS 3.4.11 update contains BIOS 116 update. As usual this can mess up with the EFI boot entries making Steam Deck unbootable, but really its only the EFI entries that are missing. Its an easy fix just need to manually recreate the EFI entries.

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

Text based instructions -

Fix for SteamOS 3.4.11 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.
