To the original poster of the thread. Can you tell us exactly what you did
during the install, i.e. let us know how you answered the various prompts.
e.g. did you tell it to use the entire disk or did you tell it to use a
certain size or percentage of the disk. The more detail you can give us as to
what you did, the better the chances of us figuring out what went wrong, and
how to fix it
