Can't boot into windows after updating

Exact same issue. My dual boot setup was working well, but a recent update changed two things:

  1. Added a new “UEFI Settings” menu option to my Grub boot screen
  2. Killed my Windows entry, resulting in the exact same issue.

I wouldn’t immediately jump to “fix it with Windows USB” since that’s not where the problem originated.

I’m also investigating. OP, as you find solutions, please share here.
