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.

Further details can be found in the UEFI specifications (section 13.3) located at

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.
