[SOLVED] Leap 15 - Windows 10 is missing from Grub menu

TYTA · 09-24-2018, 03:58 AM

Hi all,

I have made a new install of Windows 10 and then Leap 15 on my laptop. I have Leap 15 in the Grub menu but no Windows 10.

Here is what I get if I run:

Code:

efibootmgr -v

BootCurrent: 0003

It would be nice to have Windows 10 listed in the Grub. Any help would be much appreicated.

Your fdisk output shows that you have two EFI partitions (sda2 and sda8. That's wrong and may be at least part of the problem. Have you run grub-mkconfig to create a new grub menu after running os-prober?

Code:

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

Make sure your directory with grub files is actually named grub and not grub2 before running the command.
A guess at the problem is that you already had an efi partition with windows 10 (sda2) and created another (sda8) for Opensuse. You can easily verify this by booting Opensuse and mounting each of those partitions and taking a look at what files are in each.
