This is more complex... I have two drives in this system. I've got one
that holds the CentOS 7 install, and one with 6.6. The one with the 7 is
in hot swap bay 1, while the other's in bay 2. With both of them in there,
it goes to boot off what I would expect to be enumerated as hd1; instead,
it seems to see it as hd0.

When I pull out the drive with 6, 7 boots just fine. The drive with 6, of
course, has grub, while the one with 7 has grub2.

Any ideas as to how I can get it to work with the correct drive?
