I installed Linux recently on an Acer and was left with no grub menu and the below app fixed it.

https://sourceforge.net/p/boot-repair/home/Home/

This article describes using the above app or using the command line to repair grub; https://www.howtogeek.com/114884/how-to-repair-grub2-when-ubuntu-wont-boot/

Did you do manual partitioning as above? Maybe the drive/device for the boot loader isn't what it should have been. Don't know if you mentioned what you have for drives. The above has just one it looks like, sda. My laptop has two HDDs so it has an sda and sdb. I'm using sda for /, /boot and swap and using sdb for /home and the boot loader is the drive that is sda.

If I ever reinstall, the screen above will NOT have /home checked off for formatting. I'll reuse /home as /home but not format it since it has my data aka settings, config and 100+ gb of files.

You can boot off the Live USB and start to install until you get to the above screen to check what drive the boot loader is one and then cancel the installation without formatting anything and then try that boot-repair.

Here's the boot-repair dev's Ubuntu page, https://wiki.ubuntu.com/Yannubuntu & boot-repair on launchpad, https://launchpad.net/boot-repair

Thanks.
The thing about Linux (and why I haven’t used it much) is this:
In the early 2000’s I had to run linux on my Laptop. There was, at that time, no linux version that was compatible with my hardware so... I used Cygnus linux under Win 2000.
It worked fine - then, in a terminal window I tried something like COPY A -> B
It spits out a man prompt and says I don’t know what you’re talking about or somesuch.
I had to use Move to get the job done and I said to myself that any OS that doesn’t know the COPY command is BUNK!!
Very, very BUNK!
Since Linux now has a gui I decided a year or two back to try it again...
