I upgraded to Windows 8.1 and used this tutorial to fix my computer so I can boot into Ubuntu.
But for some reason every time I shutdown Ubuntu, the next time I turn my computer on it auto boots up into Windows. But when I boot into Windows, shut down, and turn my computer back on, grub2 shows up and I can choose Ubuntu. I tried installing updates for Ubuntu, and updating grub2.
Does anyone know what's going on?
