Hi,

that I maintained a multi-boot with Linux and FreeBSD was a long time
ago. I probably will do it again soon, but a step by step guide of what
I will do won't help other very much, since I've got already a multi-
boot machine, at the moment just without FreeBSD. While I'm not using
the GRUB 2 bootloader myself, I'm in favour of syslinux, especially
newbies probably should consider to use GRUB 2, by using GRUB 2 to
directly boot Linux and to chainload the FreeBSD bootloader, or after
read the manuals, to see if chainloading isn't required.

IIRC the time I had a multi-boot with FreeBSD, the default file system
for FreeBSD was UFS. IIRC Linux could access UFS, but FreeBSD couldn't
access Linux's riserfs or ext, I don't remember what file system I used
this time, it likely was ext3.

IOW each user needs to take a look at what file systems are provided by
FreeBSD and Linux and what file systems are suitable to the individual
ueser's needs.

For example, copy several Linux live ISO to a Ventoy USB-stick and make them persistent and get NomadBSD. Testing an operating system as guest in a virtual machine suffers from the limits of the virtualization, especially when using VirtualBox, let alone that anything hardware related depends on the host‘s drivers, hence you can‘t experience hardware support of the guest.

You can't compare a live CD/DVD with a persistent live FreeBSD or
persistent live Linux USB stick. While there are still some limitations
when using a persistent USB stick, it's way faster than a CD/DVD and
allows to store almost all changes.
