The commands you are pasting here make no sense to me. You are
creating a link from the usb drive to the usual place of the cdrom
drive, and then trying to mount that. The usb drive is already mounted
(you are using it to run the system). You cant mount twice a drive but
since you are doing it through the link the system might get confused.

What you need to do is create a link from the mounted point of the pendrive
check it with "df" and make /cdrom be a link to that.

Btw, I thought ubuntu mounted cdroms in /media/ so check that guide is
doing things the Ubuntu way. I might be wrong but I don't have time to
check right now.
