You should have a launcher bar on the left of the screen with a number
of icons in it, from the top: Dash, Home, Firefox, Libre Office ( 3 of
these for Writer, Calc, Impress ), Ubuntu Software Center, Ubuntu One,
System Settings, Workspace Switcher. So, do you see these ?

Along the top you should see a thin black bar with the logout icon as
well as a few others on the right. Is this also present ?

Also was this a clean creation of dual-boot and did the installation
screens seem normal, i.e. you were able to set location / keyboard etc
without any problems ?
