How to include second partition in GRUB

I have a single hard drive with two partitions, which currently looks like this:
To keep it short and (hopefully) clear, here's what happened:
- Way back I created two partitions as shown, and installed Ubuntu 13.04 onto
sda1, leavingsda2empty - I later installed Ubuntu 18.04 onto
sda2, partitioning it as shown, and moved to this as my primary OS instance - Since I'm not using
sda1any more I decided to experiment with migrating back tosda1so that I could expand to use the whole hard drive; so I backed upsda2to a NAS using CloneZilla Live - After the backup, I restored the backup on top of
sda1
This last step seemed to redo my GRUB configuration automatically, and it only shows me the entries for sda1.
Since I'm not quite ready to start working in sda1 yet, how do I get GRUB to show me the entries for sda2?

First of all, runsudo update-grub, reboot and see what happens.

@mook765 I had tried that, and it didn't change anything for me (same GRUB menu). As part of writing this question I experimented with adding thebootflag tosda6, and that seems to now boot automatically intosda6without showing GRUB. I still need to understand how to convince GRUB to show the OS's from both partitions?

I would run boot-repair as it not only repairs broken boots but also sets up grub entries automatically: help.ubuntu.com/community/Boot-Repair.
