Boot into Ubuntu Mate and run this as 'root'.

Code:
sudo update-grub

Are you pasting sudo update-grub into the terminal?

If that command isn't working try:

Code:
sudo su
Than type in your password.
Than try:

Code:
sudo update-grub
If it's still not working what is the terminal returning?

Keep in mind with Linux when you type your password in the terminal it won't show.

Can you boot into Open Suse?

I get this error message :

morten@morten:~$ suse su
No command 'suse' found, did you mean:
Command 'muse' from package 'muse' (universe)
Command 'fuse' from package 'fuse-emulator-sdl' (universe)
Command 'fuse' from package 'fuse-emulator-gtk' (universe)
suse: command not found

Yes i can boot into opensuse.

Do you mean that Windows 10 and Ubuntu Mate worked well in dual booting, with GRUB having entries for Win10 as well?

Since you installed the Suse last, I guess it is Suse's GRUB which shows up at the beginning. As it seems that Suse's GRUB cannot add an entry for your Windows, you can try to add it manually to /boot/grub/grub.cfg
Code:
menuentry 'Windows 10' {
  set root='hdX,gptY'
  chainloader /EFI/Windows/Boot/bootmgfw.efi
}
Replace hdX with your hard drive's label (e.g. if it is the first hard drive then it surely is hd0). Also replace gptY with the partition number corresponding to your EFI partition (e.g. gpt1 if it is the first partition).

If you find that there is no effect on the boot menu, just check grub's folder on the EFI partition. Some systems keep a grub.cfg there. Then you just copy the /boot/grub/grub.cfg there. Don't forget to make a backup of the working grub.cfg before you do anything .

Yes i can boot into opensuse.
suse su is incorrect.

Open the terminal in Open Suse and type:
Code:
su -
Hit Enter one time than put in your password and hit Enter.

Than type:
Code:
grub2-mkconfig -o /boot/grub2/grub.cfg
I'd be very surprised if this doesn't work. However, if it does than follow aragorn2101's instruction for adding the menu entry manually if need be.

Thanks for chiming in aragorn2101.

another option is to let ubuntu control the booting by either going into the bios and changing the boot order to ubuntu or boot up ubuntu and reinstall ubuntu grub with: sudo grub-install and rerun
sudo update-grub in ubuntu to pick up the open suse in the ubuntu grub menu.

As it seems that Suse's GRUB cannot add an entry for your Windows, you can try to add it manually to /boot/grub/grub.cfg
You aren't supposed to edit grub.cfg manually anymore as it is a generated file and will be overwritten next time. Custom entries need to be placed in the
/etc/grub.d/40_custom file. Menu entries placed here will be permanent and are added to grub.cfg each time it is regenerated.

Also you aren't supposed to refer to drive letters directly anymore as these can change. You should use the UUID of the EFI partition to do a search.

Code:
menuentry "Windows 10" {
	insmod chain
	insmod search_fs_uuid
	search --fs-uuid --no-floppy --set=root EFI-UUID
	chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}
where EFI-UUID is the UUID of the EFI Partition and can be found with blkid.
