Hello, Since 6 months i’ve had this problem that was making me angry every time i boot up my PC. It says a message saying «invalid signature detected check secure boot policy in setup » I didn’t care at the time but yesterday i tried to finally see what’s going on and tried to reset the keys and all that stuff for hours. My PC would work if i desactiveted secure boot but i would have and EDK menu every time i wanted to boot my PC and the games i play on my PC actually requires the secure boot (VALORANT). I tried everything Clear Cmos Jumper method everything but nothing seems to show up on my screen when i boot up. Can someone can help me either by sending the files for a Q-Flash or help me reset my bios in any way so i can use my pc ? PC infos : MEDION B660M DS3H AX DDR4 / MD35266 / 10025006.
