no cursor

I just upgraded from windows 7 home premium to windows 10 and as shown in the picture below, my cursor has dissapeared in the welcome back screen. I've tried everything from restarting mu laptop to changing my mouse. If there is nothing else to do is there a way to get windows 7 back?

I've been having problems with my laptop. One day it randomly turned itself off and once I turned it on I went to log on and it just hung at the welcome screen with the light blue spinner. Let me keep in mind safe mode works. I've tried a system restore but it would leave me on a black screen...
