I wrote a FreeBSD BootEasy boot into the MBR of the Windows disk and it CAN boot the GPT disk just fine. Not ideal for most, but it works well for me

I could live with that, but this is an unattended server and would experience some down time if I am not there when there is a power failure.

FWIW, here are the brief notes I made for what has been working for me for the
last year or so; most recently with a new Mini purchased about 2 weeks ago. I'm
using the entire drive for FreeBSD.


Hit Option key while booting, then select 'Windows' USB image.

Now trying GPT; looks fine, but will only boot with USB stick in
place. If it's not there, just get a folder with a '?' when starting
up.

Using MBR; boots ok without USB stick. It just takes about 30 seconds before it
actually boots.

Select YES when asked about GMT.
