Dual boot Suse 42.2 and Win10

Hi everyone;

After installation of OpenSuse, I can boot normaly on Suse, but, I can’t view “Windows 10” as option.
I have installed bootloader as /dev/sdc2 on /boot/efi and my Windows partition is an sda.

How to add windows entry in grbut2 menu?

*sry for my bad english.

Tks

First make sure that windows fast boot is off. Since EFI boot I assume you can boot Windows via the UEFI boot key. Should see which key on the UEFI boot splash screen or consult the mother board docs. Why put the EFI boot partitions on different drives. That can complicate things. Also all OS must be installed using same boot method or they will not chain to one another.

Hi gogalthorp; tks for replay.

So, this is the boot metod sugested by installer, and I change only the “/” mount.
I have tried to install boot loader in mbr but, this fail to boot, then, I have re-installed with default sugested by installer.

Oh, and my UEFI boot is disabled in my bios config.

MBR boot does not use a EFI boot partition it uses the MBR,

If Windows is installed in EFI mode Grub will not see it if installed in MBR mode. ALL OS must use the same boot method to boot correctly.Also fast boot must be turned off in Windows since it leaves the partition in a suspended state rather then properly shut down so other OS will not be able to use and thus boot Windows.

I assume you can boot openSUSE so show us fdisk -l since we can not see over your shoulder we need to see exactly what you have done.
