I was watching videos on youtube but suddenly the screen froze and a blue screen appered.It restarted and then the screen was black with some text: NTLDR is missing.Press alt+ctrl+del to restart.I pressed alt ctrl del and it restarted.It showed the same thing.I detached every usb cable connected to the pc and started it again.It booted but it was stuck in the starting windows screen. Can you figure out what happened?
EDIT
