Notice that you have *two* boot menus. Once is displayed by the firmware, and one of the entries will boot Windows "directly" and another will boot grub (the second boot menu). You configure the first menu using "efibootmgr" in Linux.
The only menu I see is the one for opensuse, where Grub Customizer would add entries.
Check the documentation of your laptop, there is always a button or key combination to reach the bios configuration and the boot menu. For example, in my tiny Lenovo laptop, I have to power off the machine, and then press a hidden button inside a hole, with a pin. Then it boots with a 4 entry menu. One option is bios configuration, another is boot menu, and the other two I forget. So, if your machine is UEFI, it absolutely has a method to produce the firmware boot menu. However, you cloned your old disk, maybe not everything is correct, and Windows can not be booted. There is a directory in the EFI directory that corresponds to Windows, it must be there in the new EFI as well. And it must be correct. I have no idea how to ensure it is correct. If it is not, it is possible that os-prober doesn't add a boot entry for it. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)
