Modify the waiting time of the Ubuntu startup interface

Ubuntu's default boot waiting time is 10s, which is relatively long, and you have to press Enter every time you start it, so I want to modify the waiting time. We can find Grub's configuration file (/etc/default/grub), where we can configure it personalizedly.

GRUB boot default startup items and waiting time

1. Modify the configuration file:

Open the grub file and modify it:

sudo gedit /etc/default/grub

The following GRUB_DEFAULT is the default startup item, generally, 0 is Ubuntu, 2 is Win10;

GRUB_DEFAULT=0

The following GRUB_TIMEOUT is the default waiting time in seconds;

GRUB_TIMEOUT=10

ctrl+x to exit, ask whether to save, enter y and press Enter to save.

2. Update configuration

sudo update-grub

Finally, if it shows done, it will be ok.
