No, this is a misunderstanding. The primary below [1] is the ufs
including my FreeBSD, it's just that Linux's parted doesn't show it
(gparted does show) and I can't access BSD by my Linux installs. And no,
the ntfs isn't Windows.

FWIW my old drives have only one primary and a extended + tons of
logical partitions, but I started to partition new drives with 3 primary
and one extended including as much logical partitions as needed [2].

To have one partition that can be accessed by the BIOS I format one with
fat32, since it can't access ntfs partitions. Most Linux use ext4 by
default, I've got ext3 and ext4, because FreeBSD can share ext3
partitions without issues with Linux.

I'm using GRUB2 from Linux to boot FreeBSD [3], it's sharing a drive
with several Linux installs, more installs anybody does need ;). I'm not
maintaining all installs.

Regards,
Ralf
