Error output by DiskGenius

FreeBSD Official Handbook said that FreeBSD can be written to USB drive by command "dd". 
But -.iso files can't boot in UEFI.
I just tested two files :
FreeBSD-12.0-RELEASE-amd64-disc1.iso
FreeBSD-12.0-RELEASE-amd64-dvd1.iso
and I Used "Rufus" to write it to my USB drive.
But it cannot boot on my notebook.Only -.img files writing USB drive can boot.
I had checked files sha236 is ok.
And DiskGenius says that my USB deive :
GPT primary database error
CRC REEOR GPT ERROR
