Hi,
after a recent Leap 15 beta update grub doesn’t find TW anymore.
What I have tried so far:
- Run os-prober. It finds the /boot ext2 partition, but then fails to recognize TW:

- I edited /etc/grub.d/40_custom and updated grub grub2-mkconfig -o /boot/grub2/grub.cfg:
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
menuentry "OpenSUSE Tumbleweed" {
insmod ext2
search --no-floppy --fs-uuid --set=root d35cbdcf-09aa-42a1-9922-e30e4a1f2421
linux /vmlinuz root=UUID=d35cbdcf-09aa-42a1-9922-e30e4a1f2421 ro quiet splash
initrd /initrd.img
}
I checked the UUID with blkid
So far no luck, the menu entry appears, but I still can’t boot.
Help is much appreciated 
My guess it is has something to do with the kernel. It’s unable to find /initrd.img, what do I need to put there?
/EDIT a little side note, oh boy, “simply type…” in the 40_custom file, very funny 
It’s like academics, “it is obvious that…”
Thanks.
David
