Hmmm ... I wonder why this happens now and after a normal update which had
triggered dracut/mkinitrd due new nvidia kernel modules. I had not get any
error message back but at boot I see a standing GRUB as the BUIOS boots by
setup from the NVME SSD ... after using the 15.2 DVD to boot the kernel from
the NVME SSD I was able to install the grub image in the rotating disk and as
with F7 or F2 -> setup in the BIOS I can boot with the step from the MBR of the
rotating disk to the MVME partition for /boot
