external recovery environment (among other things).
windows country/language screen> next
windows install or repair> repair <<< This reboots to the 1909 external recovery environment.

You should go for the Command Prompt instead of

So - first do a DiskPart in 1809 recovery environment. Then do it in 1909. Verify that C: & D: look good in both. See whether you can get it into a file, & post the contents of the file after you reboot to Windows. You would create the file with Notepad
in the 1809 environment. Then open that same file with Notepad in the 1909 environment, & add the 1909 DiskPart results to the bottom. Or just make pictures.
Edit: Come to think of it, all of the letters should show up in Notepad the same as in DiskPart, I think. But look at the DiskPart's too.
