If so, please describe. 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. > > While it=E2=80=98s possible to run one operating system as guest inside= of the another operating system, this approach has got several disadvantag= es. >=20 > > If you want to test operating systems, a starting point to do this is u= sing persistent live media. For example, copy several Linux live ISO to a V= entoy USB-stick and make them persistent and get NomadBSD. Testing an opera= ting system as guest in a virtual machine suffers from the limits of the vi= rtualization, especially when using VirtualBox, let alone that anything har= dware related depends on the host=E2=80=98s drivers, hence you can=E2=80=98= t experience hardware support of the guest. >=20 >=20 > For hardware support testing, I agree that a live CD can be useful. You can't compare a live CD/DVD with a persistent live FreeBSD or persistent live Linux=C2=A0USB stick. While there are still some limitation= s when using a persistent USB stick, it's way faster than a CD/DVD and allows to store almost all changes. Regards, Ralf
