    Does this answer your question? [How can I edit my Grub bootloader entries (Hide, Rename, Remove)? Preferably doing it manually, and not with a program](https://askubuntu.com/questions/81660/how-can-i-edit-my-grub-bootloader-entries-hide-rename-remove-preferably-doi) – K7AAY Jan 02 '20 at 23:29
  • Duplicate refers to using Grub customizer, even though also there, the question was for a command line approach. – vanadium Jan 03 '20 at 10:28

sudo nano /etc/default/grub

Add

GRUB_DEFAULT=saved                                                                                                                                           
GRUB_SAVEDEFAULT=true

After that run

sudo update-grub

Boot your desired OS.

Note that if you have a dualboot with another Linux OS, this has to be done in the system with leading GRUB2.

More info are available in the 

info -f grub -n 'Simple configuration'
