It is seen. If you hold SHIFT at boot, do you see Windows?

Open a terminal and issue the command

sudo gedit /etc/default/grub

This should ask for your password as confirmation of an administrative action and then will open an editor with the grub configuration file loaded.

Scroll down about five or six lines and add/remove '#' characters at the beginning of the next lines that it looks similar to this:

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTION=...
etc.

Then save the file and close the editor.

As a last step re-issue the command
sudo update-grub

Thanks, solved my problem by this.
