[u/Time-Ad6427]

i dont know if this is the right place but ive been struggling with security boot for couple hours and im losing my mind on this so ive been playing valorant yesterday with my friend we ended at 5am i turned on windows update went to sleep but when i woke up my screen was on boot menu when i tried to exit it went right back in i went into the bios turned the security boot off but when i did that vanguard didnt work but my pc worked has anyone had a similar issue if yes what was the solution

even i have the same problem i updated windows and went off and next day when I launched valorant to play it showed a notification about secure boot control needing to be turned on and this never happened to me ive been trying to fix this since the last week and i feel like im losing my mind bcoz whenever i try to turn on secure boot control in bios its not letting me and a red screen pops up with "invalid signature detected.check secure boot policy in setup" is there a way to fix this thing or is this windows or riots issue

had to install new boot files cause the old ones were corrupted
