I did you suggested:

# grub2-install --root-directory=/mnt/gentoo --boot-directory=/mnt/gentoo/boot /dev/sda
Installation finished. No error reported.

# grub2-mkconfig -o /mnt/gentoo/boot/grub/grub.cfg
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.14.14-gentoo
done

ls -al /mnt/gentoo/boot/

reboot the system and it still doesn't boot.
