You can describe your situation better.  What did you do and what
did what do or not do?  More detail.  You didn't even say that
you have a CD, just a file.  ???

You might want to DL a Gentoo or other "live CD" and try booting
that so it's running Linux.  Then check the "md5sum" of your
Ubunto CD, if you have one.  (Though that's easier said than
done; maybe someone will say what GUI tools will do this.)

OK, as long as the second part may be replaced with two primary
partitions.  Ususally, you'd want to have the OS installer replace
the senond part with one extended primary partition, with sub-
or logical partitions for swap and / and maybe /home.  Opinions
differ; you might want to Google for partitioning advice.
