I woke up this morning to turn my computer on, but I got a no boot devices screen which told me to insert a boot device and press and key. First of all, I have ultra fast boot enabled so my keyboard isn't enabled during startup or the no boot devices screen. I can't press the delete key on my keyboard to boot into bios because my keyboard isn't enabled. I need to enter the bios or fix the windows 10 boot problem. I've tried plugging a USB stick with Windows 10 on it into my computer, nothing happened. I've tried to unplug my boot drive and nothing happened. Help! Also, I built the computer 2 weeks ago, so I have no idea how the cmos battery could be low
