Well, it seems that grub is gone from BIOS boot partition. Mount root and show the content of /etc/default/grub_installdevice and /etc/sysconfig/bootloader.
Contents of /etc/default/grub_installdevice

The entry line above "(SECURE_BOOT="yes")" may not be correct because the machine in question does not have UEFI capability. I believe the machine is a Legacy BIOS hardware.
What are your thoughts?
So far not much. Could you show (better on paste.opensuse.org) hexdump -C -n 512 /dev/sdb hexdump -C -n 512 /dev/sdb1

Hi, I am using Tumbleweed with KDE 6 on a machine here. I decide to update the machine today by passing 'zypper dup' into Konsole. After a bit the update completed and 'zypper ps -s' said there were no core libraries updated but I proceeded to powercycle the machine.
After doing this the machine is stuck at the following displayed on screen > GRUB _
Can you tell me what may have happened and the steps to try to attempt to get this repaired?
Boot from live image, run https://github.com/arvidjaar/bootinfoscript, provide RESULTS.txt.
