Sierra installer Spinny beach ball gray screen no working mouse

[synergiance]

When I use the sierra updater and reboot, I just get to a gray screen with the spinning beach ball cursor and neither the mouse nor the keyboard seem to work. I tested the keyboard by pressing the caps lock key and the light didn't turn on.
My laptop is the HP ProBook 4530s, core i3 and standard resolution display.

If anyone knows what's up or what might fix this, I thank you in advance.
This is the El Capitan to Sierra update from the app store btw.
