That's 4 posts.

We get that it's a problem.

Somehow, grub was updated but incompletely reinstalled.

Do you use UEFI booting or BIOS/MBR booting?

[soundlord]

i don't know
MBR i think I disabled UEFI on this computer

Do you have boot media?

The install iso for Leap 15.1 or for Leap 15.2 could work. You will need to boot from some recovery media to fix the problem.

I can't remember the boot partition I used for grub...

I'm trying to read the last grub.cfg file from teh system partition...
