In the partitioning scheme, sda is HD ST1000DX002-2DV1. It has a primary

You probably want to set this partition to unused (or whatever it's
called, it's a looong time since I last did this) so that it doesn't
appear in the mount point table (eventually in fstab of the new
install). I think what you are telling it is that you want sda1 to
mounted as / IN THIS INSTALLATION and that then clashes with your new
/ (on sdc) that you're trying to install to.
In the partitionner (which is not only a partitionner, but generates the
fstab and the filesystems), you should select "dont use the partition"on
every partition which is not in sdc. Click on "use partition as" and
select "dont use the partition".
Didier, that seems to have done the trick. I apologize for having been
too hasty. Where the partitioner asks what to use a partition as, because
the top options were simply file systems, I interpreted it to be merely
for selecting file system and did not notice the "don't use" option at
the bottom. When I marked sda partitions not to be used, I was able to
save the sdc partition table and proceed with the installation.
Now that installation of ascii 2.0 on sdc is underway and before going
further I must figure out how to recover a use of partitions on sda. I
assume that were I to use the menu to revert to partitioning and restore
usage of sda partitions I'll just end up with the same problem of a
competition of sda and sdc for use of /.
When I execute a shell toward the end of installation, can I use it to
run the command "parted /dev/sda set 1 boot on" both to enable sda1 and
to make it bootable at the same time? Would the command "parted /dev/sda
set 2 on" simply re-enable the second partition? I found the parted
manual unclear on this point.
I guess you don't want to use sda from your sdc OS. Therefore don't
do anything more. When you boot the OS on sda, then, this one won't use
sdc. And vice-versa. Isn't this what you want? Or do you haved changed
the partition table on sda, or erased some partitions there which you
want to recover? This can be difficult.
If you want to share a partition (say home) between different OSes,
then, of course you have to mention it, but it's not recommendable
because config files of several applications are not backward compatible
between versions. Also private applications using dynamically linked
libraries might not find the proper version of the libraries. But of
course, it is convenient to mount the old home from another disk to copy
it to the new one to start from.
