Question Unable to turn on Secure Boot in BIOS

[Olliep]

I have an ASUS Rog Strix G513RM-“screen doesn’t work so have the use monitor!”

I’m trying to enable secure boot on my laptop but can’t do it for the life of me.

TRIED:
Opening BIOS: Boots straight to windows
Advanced Restart: Monitor No signal found, tried HDMI, DP, DP-type c Adapter, tried other monitors, doesn’t work.
Tried to reset BIOS: Laptop has integrated CMOS battery so can’t reset it.

At abit of a loss with what to do any help would be mint 👍🏼

Secure Boot must be enabled before OS installation. You can not enable it afterwards.

So, if you want to enable it, format your OS drive, jump to BIOS, enable Secure Boot and install OS fresh again.

3. Before you begin installation it is not only a good idea but is REQUIRED that you go into the BIOS (Unless you already know that it is set accordingly)
and ensure that your BIOS is set to fully UEFI compliant settings including enabling Secure Boot and enabling your TPM 2.0 or AMD fTPM device.
