Fujitsu T4020 Recovery Disc?

I have the discs necessary to restore my T4020 Lifebook back to its original settings, but it won't do anything when I put the disc in. I clicked every application, and it hasn't done a thing. I'm now prompted to make sure I want to make changes to my HD when I click a program (such as Firefox) and I always click Yes. If anybody can help me, please do so...! I even put in the Drivers and Apps CD and tried to install the Video and something else, and they wouldn't install! Thanks for any help!
