new kernel grub entries

I install often my friends Mageia Linux with legacy Grub.
They understand, and executes that upgrade the packages when see the red circle on the white exclamation mark.
But when it is kernel updates, then they no understand what the extra entries the boot menu, and not deal it and started the default old kernel.
So if the new kernel will be installed,
and made entry into the grub menu.list
Then good would be have it default also be done.
