The WiFi symbol on the top right is empty and no WiFi networks appear, I try to set one up but the "device" box is greyed out. I have Ubuntu 16.04. When I enter the command lswh -C network I get this: 

*-network UNCLAIMED

And a warning about not running this as super-user

I can access the internet if I use an Ethernet cable, or If I startup the laptop in windows 10

You're probably missing the WiFi driver. Open up a terminal and type:

sudo apt-get update
sudo apt-get install bcmwl-kernel-source

EDIT

Disabling secure boot in your BIOS is also necessary for the driver to work
