Re: efibootmgr:error failed to register the boot entry?[Solved]

Are you even booted into EFI mode? What's your

efibootmgr -v

What's your mainboard vendor? Secure Boot disabled? It could be that it simply prevents NVRAM entries from being added by external means.

You could try

grub-install --target=x86_64-efi --bootloader-id=GRUB --efi-directory=/boot/efi --no-nvram --removable

With the --force and --force-extra-removable options also available as a last resort.
