I installed Lubuntu on my Lenovo laptop to give some life into it. It works really good, but this boot menu always keeps popping up, and I wanted to know if there is any way to get rid of it? It directly boots into this menu.
Open a terminal and run
sudo -H gedit /etc/default/grub
An editor opens, and you can change the config to your liking. For example, set
GRUB_DEFAULT=0 GRUB_TIMEOUT_STYLE=hidden GRUB_TIMEOUT=0
to always select the first boot option. Save the file, and then run
to update the boot menu. On the next reboot you should not see the boot menu.
