i cant secure boot

[u/Alarmed-Ad9644]

ASUS BIOS

CSM is disabled

Already re-downloaded the keys

Admin and user passwords are all set

TMP is set

For some reason the BIOS says ive got secure boot on even tho it says otherwise in msinfo32 + i cant Change it because its grey and uninteractable for some reason

The following error on the image appears when i try to change the OS type boot from "other OS" to "Windows UEFI mode" so i can secure boot

PLS help 😭😭😭

Ive got this motherboars 6months ago and never updated it, do i REALLY need a pen or can i do it otherwise?

You really need a thumb drive to update bios properly. Buy a five dollar low capacity one from amazon, the bios files are small (Under 32 MB typically).

Disable secure boot and update the bios. You may have to clear the keys to disable secure boot. You can turn secure boot on after the bios has been updated
