Update removed windows dual boot option from Grub menu

Which grub commands do I need to run to recover the windows boot option in the grub menu?

Thanks in advance.

You updated from what to what?

The best guess would be from 15.1 to 15.2. But, in that case, you should have used “15.2” for the prefix of this thread. So that leaves us confused.

Also, how did you update? Did you use the DVD, or did you do an online update with “zypper dup”?

In any case, try as root:

grub2-mkconfig -o /boot/grub2/grub.cfg

If that does not fix the problem, then we will have to investigate more completely.
