I dual boot my laptop with Windows and FreeBSD using a single hard drive.

I find the easiest way is creating 2 new GPT partitions (1 for ZFS and 1
for swap). I then manually copy the FreeBSD EFI boot loader to my EFI
partition, by mounting the existing EFI partition that comes with the
laptop as msdosfs to /mnt, copying /boot/boot1.efi to
/mnt/EFI/BOOT/BOOTX64.efi.

Lastly, I install refind on my efi partition to allow me to select between
the Windows EFI loader and the FreeBSD EFI loader at boot time.
