Is that from UEFI boot menu or grub boot menu? UEFI or BIOS. If UEFI and UEFI boot menu, see this:man efibootmgrand askubuntu.com/questions/485261/…

You can also boot into Ubuntu and just reinstall grub. But each system with updates may reset it.sudo grub-install /dev/sdaif BIOS install and drive is sda. If not we need more info. Post link to summary report from Boot-Repair: help.ubuntu.com/community/Boot-Repair

Boot into the OS you don't want to boot automatically. Open Terminal by pressing Ctrl, Alt and t
Run in terminal:
sudo gedit /etc/default/grub
Change the line GRUB_DEFAULT=0
GRUB_DEFAULT=1
Run
sudo update-grub
and reboot.
Edit:
Note:
this is for present default OS which you don't want to be default. In your case Kubuntu.
For Grub boot menu.
When you have two Linux operating systems whenever you or the system updates grub in one OS that becomes the default, so you have to change the priorities every time. By doing the above when Kubuntu updates grub the second choice (that is Ubuntu) is selected.
