Black screen for 5 seconds then it reboots [Closed]

My pc was running perfectly than a windows update notification occured, i went along with the update and as it was restarting my screen went black for like 25 minutes so I turned it off and back on, now when ever I boot off of my UEFI its just a blank black screen for like 5 seconds then it reboots back to the bios, I don't know how I can fix it because I can't log in or anything...
