Ubuntu eats up Windows 10 - Windows not showing after installing Ubuntu - GRUB

After installing Ubuntu 16.04 LTS on a dual boot mode with Windows 10, my laptop boots directly to Ubuntu and shows no option for Windows.

The solution for this is to run this command in the Ubuntu Terminal.

sudo update-grub

Click on the search icon on the top right of your Ubuntu Desktop and type in Terminal. Click on the icon that says "Terminal" (you can also use Windows+T keyboard shortcut).

This should list any unfound OS on to the Grub list boot options.
