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.

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
