[NTLUG:Discuss] GRUB2 and multiboot

[Ralph Green]

Leroy,
  Grub2 config files are not nearly as easy to edit as Grub1.

  Hopefully, his BIOS(or UEFI) will let him select the drive to boot
from.  Until you know, it is hard to say how to proceed.   By default,
recent SuSEs have set up drives for me using their UUID.  So, it will
probably boot fine with a second or third drive in the system.  You
may not have to rerun grub2 at all, but maybe I don't know what you
are trying to accomplish.
Good luck,
Ralph
