Comment 39 for bug 1863434

Changing `GRUB_TERMINAL=console` based on https://medium.com/@leijerry888/get-grub-menu-back-after-installing-ubuntu-20-04-alongside-windows-dab5de5afc37 fixed the issue for me. However, this is still a bug.

Steps to reproduce:

1. Install Windows first.
2. Make some space on the disk for installing Ubuntu.
3. Install Ubuntu 20.04
4. On new boot, screen goes blank and boots directly to Ubuntu.
