Lubuntu mantic re-install of OS on dual boot system.

- dc7700 sda5 (no format re-install)

** Expected outcome

On reboot after install, I expected to be offered GRUB MENU with two options; prior install & this new install

** Actual outcome

On reboot this system booted without offering me choice to select which system I wanted to boot

Package `calamares` selected; but maybe GRUB related issue !

On first boot - I ran `update-grub` & output is
