Systems that boot with UEFI instead of BIOS require separate partitions 
for /boot and /boot/efi.

UEFI must boot from a FAT32 filesystem.  That filesystem will include 
the UEFI shim that's signed by Verisign for trusted boot, a version of 
GRUB2 that's signed by Red Hat (IIRC), and the GRUB2 configuration 
file.  The /boot filesystem will contain the same thing on UEFI that it 
does under BIOS, namely the kernel and initrd.
