If you use GPT, you will need a FreeBSD boot partition unless you have some other method of booting from a USB stick.
Are the two FreeBSD installations for the same architecture or two different, like maybe amd64 and i386?
Grub2 can't boot FreeBSD 9.1 and 9.2 as it does with FreeBSD 10.0-STABLE and 11.0-HEAD.
set root=(hd0,gpt2) # or wherever it is
But if you can boot one, you may be able to boot the other.
If architecture and kernel are the same, escape to loader prompt and
This will ask for root partition, such as
ufs:/dev/ada0p2 (or wherever it is)
If the kernel is different, copy from second installation to a different subdirectory on the first, and/or give the kernel a different name.
Then, at the loader prompt,
boot /path-to-second-kernel -a
and specify the root partition at the mountroot> prompt.
I have done this, but have not tried this on crossover between amd64 and i386.
