Yes, I've read about that and the fact that it has been quite hard. This
actually did surprise me a bit, considering that UEFI has been around
for a while now.

This sentence actually rather suggests that you have not read my post
(properly) before answering.
Please don't get me wrong! I appreciate any help anyone offers me and I
will not complain if noone can help me or if the ideas someone had don't
lead to the desired result.
In this case, I really went out of my way to make it overly clear, that
I was booting me computer in EFI mode and that the boot menu is from the
mainboard's firmware and offered before a single access to the SDD has
been made. I would get this boot loader (or boot menu) if I removed all
drives from my system and pressed F12 while starting the system.
Why would you therefore assume I have installed an EFI FreeBSD on an
BIOS system? I have never tried that, so I don't know if that would even

To do that, I'd also have to reinstall Windows because currently
everything is in EFI mode.
And it does offer a little something that I currently do not have: More
time. If I miss the right moment, I can't choose the OS, the computer
just boots up Windows as this is the default and I cannot set the
default to FreeBSD.

I have actually considered this and decided not to do it.
