chroot into the boot disk and then run the following commands:
zypper install -f grub2* zypper install -f shim* /usr/sbin/shim-install --removable grub2-mkconfig -o /boot/grub2/grub.cfg
Cause
"symbol `grub_efi_allocate_fixed' not found" is referenced in /boot/grub2/x86_64-efi/grub.efi and /boot/grub2/x86_64-efi/core.efi. Those files are not updated when grub2-* rpm packages are installed until a grub2-install updates/creates the files. If this is not happening, then the system would run into a symbol error when grub tries to load.
