[arch-general] Editing grub for dual boot?

[bill]

    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
