gigabyte Gigabyte Z690 Gaming X - Setting platform key in Bios Secure boot unable to POST

[Adrian Hartanto]

Spec:
- CPU: Intel i5 12600KF
- Motherboard: Gigabyte Z690 Gaming X DDR4
- Ram: Corsair 2x16 GB DDR4

- GPU: Gtx 1060
- Storage: Samsung EVO 850 250GB (It's MBR)
Please need help. My PC won't go thorugh POST.

Previously, Bios is working and setting CMS to Legacy enables me to boot to Windows 10.

So I was trying to upgrade to windows 11 and I need to set secure boot for it.

So I was following a video on setting Platform Key in the bios, disable CMS and Save changes and exit. (My whole purpose is to enable secure boot)

But after that my PC won't go through POST.
And I'm stuck with no solutions yet at the moment.

 

I've tried resetting CMOS and jumper many times. but it didn't work.

Motherboard shows that the beep stucks at VGA red light

Solved by updating bios to a newer version with Q-Flash Plus from Gigabyte.
It will reset the BIOS to factory default
