Last night I just shut down my Nitro 5 with its update. The next day I open it, it shows the blue screen with the error "Innaccessible Boot Device", after my laptop restarted thrice automatically after each blue screen. It is now stuck on the preparing automatic repair window.

I've been trying to boot to advanced startup to delete the update but I don't know how to since the shift+f8 does not work.
