Same problem. It happens when I installed Ubuntu 18.04.1 over Windows 10 to make it dual boot. Everything works fine, until you press enter on the main grub but as soon as you press down key to select other option, it Grub screen freezes and you have to press force shutdown button from CPU.

Did anyone found solution for this?
