If you run update-grub, do you see a warning that os-prober will not be
executed? After installation or upgrade to grub, os-prober is disabled
and will not detect Windows or any other OS that may be installed.

The answer is to modify /etc/default/grub and run update-grub again:
To restore the old behavior, open a terminal and issue sudo echo
GRUB_DISABLE_OS_PROBER=false >> /etc/default/grub && sudo update-grub
Note that you will need to do this again when grub is upgraded.
