I installed 18.04 after 14.04. The default grub entry was 18.04 and 14.04 was displayed below. After a 14.04 update, things changed.

Instead of booting into 18.04 advanced options and choose the first kernel before last and then remove the last linux image and headers, reboot again in ubuntu 18.04 and make an update to the last kernel.... I tried to delete the unused linux image and headers hoping that will do the job. It didn't.

I tried 'sudo update-grub' in ubuntu 18.04 and then reboot, but no change. (I use 18.04 ubuntu-mate and 14.04 ubuntu).

Is there a way to put 18.04 as default, besides waiting for a new kernel update in 18.04?

load up grub-customizer, and set the default boot entry.

In versions newer than 18.04 grub-customizer is in the repositories, and can be installed with

sudo apt install grub-customizer

For older versions

Then right click on the ubuntu version you want to load by default and move up in first position. Then save and reboot.
