Hi there,

as this is probably interesting for others, too, I want to add the changes in `90_mender_boot_grub.cfg` that made it working for me.  
The changes are inspired by the current `boot-menu.inc` file

> <https://github.com/Wind-River/meta-secure-core/blob/master/meta-efi-secure-boot/recipes-bsp/grub/grub-efi/boot-menu.inc>

which is replaced by this `90_mender_boot_grub.cfg` file.  
Basically, two things changed:  
The `mender_kernel_path` is cleared in order to use the kernel in the boot partition (efi) and the grub search command helps to find the right partition without hardcoding.

             initrd "${mender_kernel_path}/${initrd_imagetype}"

```
