Then this probable is a case of not installed and not (by default) enabled os-prober. So install os-prober if it's not already. And in /etc/default/grub GRUB_DISABLE_OS_PROBER=false And last sudo update-grub os-prober won't be enabled by default anymore. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1038974
