Hi, I have installed ZorinOS 16 on a separate drive and windows 10 on another drive. when I update grub it does not see the windows boot manager. I remember that you need to install a few programs to have grub find the windows boot manager but don't remember which ones I need. Zorin is on the first …

Can you please open a terminal and run (Please ensure your windows drive is plugged in and running): sudo os-prober If Windows is spotted, then run sudo update-grub and relay your results?
