I got testdisk.  It seems to be an uber version of gparted.  It also 
seems dangerous!
But it does not name the operating systems on the various partitions.  
 From ubuntu
or debian I can look at files in the various partitions.  Which file(s) 
contain the name
of the operating system that's installed in a given partition?  
Someplace that info
must exist, since grub (_not_ ubuntu grub!) uses that  to name the 
systems you
can select at boot.

My install of Ub 10.10 is all screwed up.  I have it, but it's installed 
in the wrong
partitions; it can't see PCLinuxOs, which should be on extended sda5 and 
where sda6 is swap.  I can see those partitions, but I can't boot to 
that os,
And Ubuntu grub shows about 6 versions of Ubuntu--maybe 8, I lost count
before it timed out. I can see Debian, but the booter doesn't name it. 
I've got to straighten this all out, and go back to the boot manager in 
which I had to do with the last Ubuntu.  It could see everything, and 
only once.
After I unmangle the partition mess, if I can.

FWIW, however, 10.10 _did_ save my 10.04 configuration, if anyone is
interested.  I was somewhat surprised.

Thanx for your patience, guys and gals.  I'm just muddlin' thru.
