How to boot

[ykla]

Hi !

I using FreeBSD with ZFS, UEFI and GPT now. 
…………………………………………………………
list:

    my disk partitions :

100M   EFI partition  Fat32
120GB  / root partition ZFS
8G          Swap 

FreeBSD 11.1 amd64 
………………………………………………………
     I can boot my FreeBSD in chainloader only. 

    I try to install grub2 so that I can boot my FreeBSD directly. But I met 
some trouble when I make it. I don't know how to write configure files. Here is 
no Handbook for me, and none can tell how to do it. 

    And the FreeBSD developer said to me that I should complain for you. 
Because they said Grub belongs to GNU plan not BSD project.

    So in this way how can I boot my FreeBSD directly ?
 
    Thanks.

yours,
ykla
