Via the loopback command, GRUB2 allows to directly boot an ISO file.

Now, I've configured the according menuentry to boot the PC-BSD Live DVD ISO, but when I try to boot it, the FreeBSD bootstrap loader outputs:

can't load 'kernel'

Here is the GRUB2 menuentry I currently use:

menuentry "PC-BSD" {
        search --no-floppy --fs-uuid --set root 0d11c28a-7186-43b9-ae33-b4bd351c60ad
        loopback loop /PCBSD9.0-RC1-x64-DVD-live.iso
        kfreebsd (loop)/boot/loader
}

Does one know how I'd need to amend that in order to be able to boot the PC-BSD live system?

After "can't load 'kernel'" you get dropped to the loader prompt.

It has an ls command, so you can check where your kernel is and load it with load and then boot.

Also you can try to boot the kernel directly, by trying something like kfreebsd (loop)/boot/kernel/kernel.

Little late, but I just saw your answer. ls gives open '/' failed: no such file or directory. I wonder how the loader works while (apparently) no root is found? –  user569825 Apr 22 '12 at 20:15
