Change default entry on GRUB menu

#tutorial #ubuntu #grub

By default, the first element in the GRUB menu will be selected after the seconds at GRUB_TIMEOUT has passed.

In order to change the default selection we need to modify the GRUB_DEFAULT property at /etc/default/grub.

All the entries at the GRUB menu are numbered starting from 0.
So if our menu looks like the following:

Ubuntu
Advanced options for Ubuntu
Memory test (memtest86+64.efi)
Memory test (memtest86+64.efi, serial console)
UEFI Firmware Settings
Windows 10
Enter fullscreen mode Exit fullscreen mode

If we want to make the Windows 10 entry the default one, we should set the value as 5.

sudo vi /etc/grub/default
Enter fullscreen mode Exit fullscreen mode 
GRUB_DEFAULT=5
Enter fullscreen mode Exit fullscreen mode

Once you've made all the changes, you should apply them by running the following command.

sudo update-grub
Enter fullscreen mode Exit fullscreen mode
