So, the next step was to clean out the other distros. I used gparted to delete no longer needed partitions and to expand other partitions to fill the space. All is now good. I then ran #update-grub hoping that would regenerate the grub boot menu, (I also tried #update-grub2) but the old entries still appear when the system boots.
Are you talking about entries in GRUB's menu or in the UEFI boot menu ? update-grub only updates the former. What is the output of "os-prober" ? Are you sure the GRUB that shows up is the one from Debian ?
