Hello.
I am a Linux newbie, so perhaps my suggestion will be a little naive, but
anyway.
When the setup script prompts you for the disks to install, are you entering
"x" or "x1-x5" From the wording of your posting, I wasn't sure if which one
you had entered, if the latter, try the former and see if it works.
Good luck, and I hope someone will post a better answer than I.
Be happy....
