Boot into the BIOS setup and somewhere in there you should find a Boot
Order setting.  In there check that the CD is shown before the HDD.
Alternatively one of the options shown on booting (in the BIOS startup
screen) there may be an option to Select Boot Device or something
similar which will allow you to select the CD for this boot without
affecting the BIOS settings.
