Change GRUB boot order in Ubuntu

With Ubuntu, you can change the boot order of the GRUB menu. This is useful if you have multiple operating systems installed on your computer and you want to change the default boot order. In my case Windows 11 and Ubuntu 24.04.01, the default boot order is set to Windows 11. If you want to change the default boot order to Ubuntu, you can follow these steps.

Change GRUB boot order

sudo nano /etc/default/grub
GRUB_DEFAULT=4
sudo update-grub

windows set as line 4 so change it to 0 for Ubuntu.
