Have you tried looking at your system using EasyBCD?
It's a program that lets you easily manage your boot settings.
I found that it may make a difference which OS, you are running it from so you may have to try installing it and running it from from both.
For me it didn't work when running it from Windows 8, but when I did it from Windows 10 as well, it worked fine.
It's possible that what I did it just set both OSes so that the boot sectors matched, because I did it from 8 and then 10.
But I've used it many times over the years, it will at least let you look at what your boot sector is showing.
The edit boot menu tab, lets you decide which OS it will log into by default, and whether to show the boot menu or not, the add new entry lets you add another OS.

If you look at the bottom of the screen on the right and follow the links you will see that they are offering a free boot repair DVD .ISO for Windows 10, which I am downloading right now.
