Help

HI I have problems with booting up on Gigabyte Aorus 16X 9KG laptop. Unfortunately it does not allow me to Turn Off SB and I am dual booting with Win11.

error
error960×1280 207 KB

That’s what I am getting when trying to boot from USB on bot NixOS 24 and 25-beta made with following tools:
1.Rufus
2.Balena Etcher
3.Ventoy

All I am getting is error above.

Are there any solutions for that?

It seems you first need to enable advanced Mode in the bios. After that you need to disable csm. Than there should be a secure boot option.

thanks for help actually I managed to do that but I forgot to disable BitLocker so for some time I could not figure out how to make it work and now I am dual booting W11 and NixOS with Refind Bootloader with noe bigger issues :smiley:

EDIT:
So others know how to get into “Hidden BIOS” Menu on that laptop and possibly other Gigabyte’s:
1.Go into BIOS
2. IMPORTANT!! WITH MOUSE choose Peripherals > NVME Settings > Click ESC and it should show you that Menu.
There you should be able to see all kinds of Hidden BIOS settings
