grub-install: error: efibootmgr failed to register the boot entry

This document (000020644) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 15 
SUSE Linux Enterprise Server 12

Situation

While installing SLES 15 SP3 on PERC VD with secure boot option disabled in the installer, the error
"efibootmgr failed to register the boot entry"
was observed causing the installation to fail.

Resolution

For UEFI boot, the system partition must be located on a primary partition formatted with a fat fs, and contained on a MBR or GPT labeled drive.
Further details can be found in the UEFI specifications (section 13.3) located at uefi.org.
The current version of the UEFI spec PDF (at time of writing the article) is available at: https://uefi.org/sites/default/files/resources/UEFI_Spec_2_8_final.pdf

Cause

Reason for the failure mentioned above was an attempt to install where /boot/efi was located on a logical partition (/dev/sda5). This violates the UEFI specification.
