Details:

When iPXE booting a UEFI host to a GRUB menu, I receive the following error:

...
Filename: boot/grub/x86_64-efi/core.efi
tftp://x.x.x.x/boot/grub/x86_64-efi/core.efi... ok
core.efi : 206848 bytes [EFI]
Welcome to GRUB!

error: sector sizes of 1 bytes aren't supported yet.
Entering rescue mode...
grub rescue> 

The netboot directory was created using grub-mknetdir version 2.02~rc1

The same configuration is able to service legacy (BIOS) based hosts
successfully.

Please let me know if there's any further information I can provide (or
gather) to help clarify and/or resolve this issue.
