Hello again!Thanks much for the warm welcome and good advice.I have another issue in that i seem unable to have both arch and ghost bsd on the same system/drive. If i install bsd last the boot manager sees but cannot boot arch. If i install arch last, grub doesn't see the bsd at all.Apparently i need to edit grub so as to point it to the second os. Does anyone have advice how to do so, or references to a wiki, etc? Any thanks!peace-bill
To boot FreeBSD I needed to add a chainloader to the Linux's grub.cfg.
menuentry "FreeBSD"{ set root=(hd0,msdos1) chainloader +1 }
Note, at least FreeBSD needs to be on a primary or GPT partition.
Hi all,
BSD is on a primary so that's not the issue.
When i added this to grub.cfg it puts the bsd option in my grub at bootup, but when i select it i get the error "invalid signature." I tried replacing msdos1 with msdos3 since my bsd is on the third primary partition, but same result. I have checked the syntax several times. Does this error have to do with my placement within the file (near the end before memtest) or another error? Many thanks! peace -bill

You might have to mark the partition as active/bootable and you might have to hide other partitions.
It all depends on what the bsd is expecting to find in regards to partitions. I've never used it so I can't be of much help besides guesses.
I have another guess.
BSD uses partitions within partitions (it calls them "slices".) Check under the GRUB command line for anything funky like hd0,msdos1bsd1 or something.

Did you try running
# grub-mkconfig -o /boot/grub/grub.cfg or, for UEFI-GPT Mode (As per #Alternative install method):
# grub-mkconfig -o /boot/efi/EFI/GRUB/grub.cfg after installing bsd? Often it recognizes other OSes on its own. If not, installing os-prober and running grub-mkconfig … Again might help.

Do you have os-prober installed?
https://wiki.archlinux.org/index.php/GRUB says, in part:
Dual-booting Tip: To have grub-mkconfig search for other installed systems, install os-prober.
I used architect to install this time, and os-prober wasn't installed by default.
