Welcome to AskUbuntu. Can you please edit your question and add more details like your system specs, model or anything else that might help us help you. Unfortunately, Dell PC could be any number of Dell models that are out there. Add in if you added any addition video cards, etc. What version of the kernel works for you? Any more details would be greatly appreciated. Thanks!– TerranceNov 29, 2021 at 15:33

I hope I understood correct you question. Please add to /etc/default/grub
GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true
then run afterwards
sudo update-grub
Boot up your desired kernel and for it will be set as default the following boots.
For explanation please read
info -f grub -n 'Simple configuration'
