Thanks, Didier,

In the partitioning scheme, sda is HD ST1000DX002-2DV1. It has a primary
partition that is bootable and the mount point /. When I edit this
partition, it says it is on sda.

Disk sdc is ST1000MN0011, and it also has a bootable partition #1. When
I edit it, it says I'm editing disk ST1000MN0011 partition #1 of sdc. I
give it / as mount point, make it bootable, and the label "root".

Partition #1 on sda is has mount point /, the mount options I leave as
the defaults, label I left out the label, but now label it "root". This
should make no difference as far as I can see. I leave typical
usage as "stardard". I don't know what standard options refers to, but I
should think standard option would not cause this disk to interfere with
others.

But I get the error, "Identical mount points for two file systems."
