I have 2 disk on my computer; the first with Windows 10 (/dev/sda) and in the other Ubuntu(/dev/sdb). Here some image about my disks:
Grub is installed on /dev/sdb but in Grub menu does not appear Windows 10 to start.
How I can add an entry for windows 10 into Grub?
I already tried with this, but does not works for me: Add windows to my boot menu
sudo update-grub
?sudo update-grub
