Grub 2 Does not recognize Windows 10 Pro

I have a Desktop Computer, and in it are an M2 drive with Linux Mint and Ubuntu Studio. Also in the this computer are 5 other Drives. I have 4 - 2 TB Drives and 500GB SSD, and Windows sits on the SSD. When I do an Update for The ISO that sit on the M2drive or do an ‘sudu update-grub’ it find either of the ISOs on M@ but it never finds the Windows OS.
Any help here would be very helpful
