Disc read error on bootcamp. No way to restart

Hey.

So i got the dreaded disc read error on bootcamp windows on my mac. It says I should press ctrl+alt+del but I can’t. No way to do with my laptop keyboard. A keyboard from my pc doesn’t work with it (it works with my gf’s macbook).

Also power button doesn’t work. I can press it but it does nothing. The laptop won’t power down.
