Other than you, I don't install a bootloader for each install. At least
other Linux usually allow to install no bootloader at all. However, even
enforced installs of a Windows or FreeBSD bootloader didn't cause an
issue.

That's the only really issue that still exists, since this is beyond
me, too. I'm an experienced Linux user, but not an experienced FreeBSD
user.

No, nothing changed.
