Dear medion community, After updating my bios yesterday (motherboard MB ECS B760H7-EM V3) to this version found here -> https://www.medion.com/be/nl/service/product-detail/10025303/0571938617 my pc wouldn't let me boot without disabling secureboot because I keeps saying that there is a invalid signature detected, I've tried a lot of things: restore the factory keys, reset to setup mode, removing CMOS battery for 5 minutes and reinstalling the update. Nothing worked so far and I ran out of ideas, can someone please help me. Thanks in advance! Stijn
