As stated above, it gives out blinking codes of 4 slow blinks, then stops, then it gives 5 to 6. I can still see the screen boot up and can still see the HP logo on screen. It says "no bootable image found" I tried booting in legacy mode which gives me "No operating system found." I pretty much don't know what is going on. It was working fine as I was watching a video, then I went to the bathroom, came back and it had the error showing up. Anyone have any ideas?
