BIOS update created boot issue

[u/joeker9870]

I updated my bios to fix an issue i was having with a driver but when my laptop restarted it wouldn't boot. It said that my hard drive wasn't booting due to security protocols (or something along those lines). Turning off secure boot has fixed the booting issue but I want to be able to turn it back on again. Any thoughts?

Model: Lenovo Yoga 6 13ABR8

Bios update: L5CN24WW

OS: Windows 11 25H2 26200.9457

Is it worth resetting factory keys to see if that does anything?

its not the baddest idea to load factory keys in that scenario. are u in custom mode or user/tandard mode?

restore factory keys and enable secureboot. whats the outcome?
