All windows entries return to grub

Question

When trying to boot into windows 10 from grub on my Ubuntu 19.10/Windows 10 my system instead swiftly returns to grub as though I had just booted.

I have tried all of the following :

• running sudo update-grub
• running sudo update-grub2
• following these instructions
  following the "boot repair" section of these instructions plus some extra options ; [pastebin output]
• List item

Possible causes
Prior to my discovering this issue but after my last successful Windows boot (that I remember)

1. Updated to Ubuntu 19.10 from 19.04
2. Reactivated certain Windows features (system protection, hibernation, page files)
3. Other steps detailed in comments on this question

Thank you in advance.

Answer 1

I don't know why this worked or if it will for others but I was able to fix my issue by using the purge grub and reinstall option in the boot repair program.
