i opened my laptop and it said no bootable device available, so i followed the steps to open BIOS and reboot via legacy (i have no idea if im using terms correctly i know nothing about software) and i ended up with the three options to reboot with but NONE of them work and i cannot return to the main BIOS screen because its not letting me. when i turn my laptop off and on the black screen with writing shows up and idk what it means please help me if you know what to do i tried slotting the hard drive in and out of the gold teeth but it did nothing i also could not remove the hard drive bc of a really stubborn screw

I ALSO DONT KNOW HOW TO USE REDDIT AND IDK HOW TO UPLOAD THE PICTURES
