As has already been mentioned by NoOp, blkid is installed by default and
should have given you output. It may become important to find out why
blkid doesn't work on your system. You also could have browsed to the
/etc/blkid.tab and looked at them in there.

Of course it did, the command that would have not given you UUIDs was
fdisk -l, alternately, you could have just browsed to the location in the
/dev folder and seen them there.

This looks like you followed an appropriate method however it's general
and we probably need to check specifics at this point.

Post your real fstab (filesystem table), and also the two partitions, as
below.

This topic started out talking about a 33G partition on which you
installed Ubuntu, then you tried to carve that into two partitions. 

What are those two partitions, is one the hdc8 that you mention in this
quote? "I have now managed to get the particular (hdc8) partition mounted,
and writable, and written to, in Debian, but I now do not know how to get
the file mounted in Ubuntu" It's not clear to me what "file" you are
referring to in that comment.

So, list the two partitions you want to mount at boot so we can compare
them to your fstab.

No need to reboot, after saving your changes to fstab, issue the command,
as root(sudo), mount -a. That will mount all the filesystems marked auto
in the fstab.

Can you mount both of them manually? What command do you use for mounting
and, after you've mounted them, does the output of the mount command with
no options show them as mounted? Does fdisk -l show them?
