How to disable secure boot on Thinkpad T420?

I installed Debian 10 on my Thinkpad T420 but when i try to boot i get 'Missing operating system'. I think the problem got something to do with enabling UEFI mode and disabling 'secure boot', but in the bios settings i don't see option for secure boot. Is there such a option?

T420 does not have any Secure Boot option, because it doesn't support Secure Boot.

And we're back...
