I think to load from the CD/DVD the computer needs to read from that drive before it tries to read from the hard drive (which is the one with errors). There should be something in the bios settings I think to do with boot order - how to get in to bios settings varies by computer so either google it from your trusty XP or else watch the Win7 one as it boots and hope you spot a message (bottom left of screen) which says something along the lines of "press F2 to enter settings" (going from memory here). Hit (gently!) the appropriate key repeatedly to interrupt the boot sequence. You'll be presented with a basic DOS screen which you navigate using the keyboard. You need to change the boot order to look at the optical (CD/DVD) drive before any of the hard drives. If you can manage to do this you might find that if you place the disc in the drive and reboot, you can reinstall/repair from your CD/DVD.
If the boot order already has optical before hard drive then there's something else going on - perhaps some malware or else the optical drive might have failed.
I find the moneysavingexpert techie stuff forum (google it if unfamiliar) very useful for computer issues.
