Hi again
I haven't ever seen that particular "pending" error before for sfc, but I looked around, and evidently quite a few folks have run into the same problem. A helpful tech was nice enough to provide us with a DISM command that can help clear up the error. Here is that guide:
[FIX] There Is System Repair Pending Which Requires Reboot To Complete
I think what you could try next (if your Internet is stable enough on the affected OS) is to use that same DISM tool, but this time using a different command:
Running DISM online
1)
Right-click the
Windows Start Menu icon
2) From the menu, select
Command Prompt (Admin)
3) To the question "
Do you want to allow this app to make changes to your computer?", select
Yes
7) Type in the following command:
Dism /Online /Cleanup-Image /RestoreHealth
This can take quite a while - it varies a lot from machine to machine, and the speed of the Internet connection can add extra time when slow. Even if the "Percentage Complete" stops for a long time at a certain percentage, wait it out: it's fairly normal for the percentage displayed to not get refreshed for quite a long time.
_________________________
If the DISM system health restore finishes successfully (it will say so if it does), you can then try another run of the SFC tool if you'd like. If it finishes without errors, then things should be looking up.
To be extra-thorough, you also might want to try forcing a CheckDisk on the hard drive holding the troubled Windows 10 installation ... just to make sure that the NTFS file system is ship shape. You can schedule that from within an elevated Command Prompt, using the chkdsk /r command, then allowing it to run on reboot.

I still think that only having one Windows 10 installation on the computer would be more efficient & less prone to strange behavior that might send you on regular visits to our forums :)
Good for comedy though, yes? .... (my kids tell me I'm as goofy as I am grumpy, and I tell them it's one of the privileges of old age)
