EFI boot process is done before the grub config comes into play, and the 
grub config has a few extra lines in it. The machine I'm testing on when 
you goto the boot menu will show UEFI: $CD_DEVICE_NAME or for boot 
entries for ovirt it would show:  oVirt Node Hypervisor If your grub cd 
supports efi booting it will be noticeable in the boot menu. In order to 
do an efi installation it has to be booted in efi mode for it to 
properly setup the boot entries.
