I don't quite understand the question. If all you want to do
is get access to your Windows drives while running Ubuntu,
this should already be set up by default. You do not need to
"create a partition" in order to mount a partition. You only
need to mount the partition at some directory on your file
system. This directory would be referred to as a "mount point".
