I have reinstalled my HP laptop and everything worked just fine. Then i went to the drivers section and downloaded a bios update. The update downloaded and i started the program. The program told me something that he cannot flash bios because of someUEFI issue. But there was second uption, Only flash bios. So i chose that , it installed but after reboot i get only black screen. With caps lock light blinking 5 times fast 3 times slow.
I tried holding Windows Key + B while booting. But that did not help. My laptop is an HP 17-Bs044nb . I'm running windows 10.
