You need to mount the EFI partition to /boot/efi in the installation
system.  As the manual says in "Preparing for Installation" (perhaps not
clearly enough):

   If you instead wish to use EFI-based GRUB, a FAT32 “EFI System
   Partition” (ESP) is required.  This partition should be mounted at
   ‘/boot/efi’ and must have the ‘esp’ flag set.
