Hello everyone.
I recently install FreeBSD 11.0 in my computer, which has two HDDs, one hosting Arch and the second one FreeBSD. I'm using the Arch's GRUB2 to boot, it does work with Arch but not with the BSD. I configured GRUB2 following this excellent article https://wiki.archlinux.org/index.php/GRUB . I edited /etc/grub.d/40_custom, adding this entry (this is the current one):
menuentry 'FreeBSD' {
insmod ufs2
set root='hd0,1'
kfreebsd /boot/kernel/kernel
kfreebsd_loadenv /boot/device.hints
set kFreeBSD.vfs.root.mountfrom=ufs:/dev/ada0s1a
set kFreeBSD.vfs.root.mountfrom.options=rw
}
and also tried chainloading:
menuentry 'FreeBSD' {
insmod ufs2
set root='hd0,1'
chainloader +1
}
but GRUB is telling me all time that the file /boot/kernel/kernel doesn't exist (which is not true, because I booted into FreeBSD changing the boot order in the BIOS), however, it does recognize that /boot is a directory and exist.
Any idea of what is happening here? Thanks a lot in advance.

I have solved the problem, and I'm really confuse now. What I did was to change the HDD entry in the GRUB config file /etc/grub.d/40_custom, for this one:
menuentry 'FreeBSD' {
insmod ufs2
set root='hd1,1'
chainloader +1
}
In my search on the internet I found a lot of outdated information and sometimes even contradictory, but I don't understand why in GRUB hd1 = /dev/sda and not hd0 = /dev/sda?

I can only guess that for some reason, GRUB considers the FreeBSD disk as the second disk. What happens if you unplug the Arch HDD?

Here I have a little bit of a problem, because both HDDs are identical (in the sense of vendor, branch etc) so I wouldn't know how to distinguish physically between them. This uncertainty is not self-inflicted: I received this old PC from a friend.

With the PC powered off and its power cord unplugged, unplug one hard drive, power up and see what boots. I realize I may be stating the obvious.

Sorry for bumping and hijacking the thread, but i having same issue...

Only progress i made is a very weird terminal with malformed buffer on top of the screen...
Any help is welcome.
