Try removing the
installation CD and then restarting your computer. Once the
computer has restarted, re-insert the CD and wait for the
CD menu to appear. When the menu appears, click just once
with the left mouse button on the top installation option.
You should now wait for the installation to start. Note that
depending on the speed of your computer, there can sometimes
be a delay between clicking on the CD's install option and
the actual installation window
appearing on the screen.
