Im new to Linux and i faced a problem during dual boot windows and linux in separate disks.

In the grub menu windows doesnt appear and only ubuntu appears. But if i go to boot menu and change UEFI mode to Legacy mode then Windows starts automatically after reboot.

    Ubuntu must have been installed in UEFI mode, while Windows is in legacy, in which case what you describe is the expected behavior. Not sure what's the question here. – mikewhatever Dec 14 '19 at 14:07

Both / All OS's must be installed in same mode. So if Windows is allready installed in Legacy mode, Ubuntu must be too, for both to show up in GRUB menu. And visa versa.
