Where the heck is GRUB?
Why don’t I see GRUB?
I have GRUB, obviously:
grub-install --version
grub-install (GRB) 2.12-1ubuntu7.3
https://askubuntu.com/questions/182248/why-is-grub-menu-not-shown-when-starting-my-computer
Also get rid of annoying login
I turned on automatic login in Settings | System | Users
Set up GRUB to display indefinitely at boot
sudo nano /etc/default/grub
Change:
GRUB_TIMEOUT_STYLE=menu
[changed from =hidden]
GRUB_TIMEOUT=-1
[changed from =0]
sudo update-grub
WARNING– os-prober will not be executed to detect other bootable partitions. Systems on them will not be added to the GRUB boot configuration. Check GRUB-DISABLE_OS_PROBER documentation entry
update took 2 tries, probably I made some sort of typo
