This post relates to an unresolved question posted yesterday (https://forums.opensuse.org/showthread.php/512546-Restoring-Leap-42-1-to-Bootloader).
Current system: SuSE 13.1 and Windows XP; 13.1 bootloader set to default to 13.1, with option for XP.
To access a recent installation of Leap 42.1 no longer accessible in the YaST bootloader panel, I modified /etc/grub.d/40_custom, but grub2 is not obtaining the images.
Files in /boot/ in Leap 42.1 installation:
