Blue Screen Kali

So I was in the middle of sudo apt-get upgrade and a meterpreter thing I had been testing on my pc and Iceweasel. It started to run quite slow to the point where I could barely move any windows and then virtualbox gave me this error

So I logged back in and got this

If I try to open a terminal (windows key + s then type terminal) it goes back to the error. I've rebooted my pc.
