On both surface Pro and Pro 3 it worked with the following partition:

/dev/sda1 ef00 fat32 512MiB

Grub2 was compiled with device-mapper USE flag and GRUB_PLATFORMS="efi-64"

And installed with 

# grub2-install --target=x86_64-efi --efi-directory=/boot/efi --boot-
directory=/boot/efi

What exactly is the problem?

Grub2 succeeded in installation? If yes could you give the efibootmgr output?
