Risks of UEFI update or not-update?

I could update to Secure Boot 371 with the firmware updater. I’m on version 217. I’m only using Garuda but I have a second SSD for another Linux later. I don’t want to find out that I can’t get back into my system if something goes wrong. What does the update mess with?

This here sounds like I should upgrade:

Insecure versions of the Microsoft Windows boot manager affected by Black Lotus were added to the list of forbidden signatures due to a discovered security problem.This updates the dbx to the latest release from Microsoft.

Before installing the update, fwupd will check for any affected executables in the ESP and will refuse to update if it finds any boot binaries signed with any of the forbidden signatures.Applying this update may also cause some Windows install media to not start correctly.

Not aloud. :grin:

You can chroot via live ISO and repair grub, just search in forum.
Back up your important data.

Maybe you miss, Garuda Linux dos not support dual boot with M$.

At least, we’re missing your garuda-inxi.
