After upgrade to 19.10 on my dual boot system I am unable to boot into Windows.
If I change boot order in the BIOS and put windows boot manager first I can boot into Windows no problem.
However... from the grub menu when I select Windows boot manager the screen flashes and I'm back at the grub menu. So I do see Windows as an option in grub, it just doesn't boot.
here is the log: https://paste.ubuntu.com/p/rJPfP9WwSs/
