I forgot to say: to get out of grub-emu you need to press c to get an (emulated) GRUB prompt, the type: exit
3. Meanwhile, you can use grub-emu to display the Grub boot menu in a console or in an accessible graphical terminal: _ install grub-emu is not yet done _ type as root or using sudo: grub-emu This will display the menu of grub as currently set up in an accessible fashion. You can navigate as if you were in the "real" grub menu to check the labels of the menu entries and their order, so you will know how many "down arrow" key presses you will need to reach a specific boot entry.
