Windows xp installation cd not detected on start up

[berg2010]

Hello, I am getting the following error message:
"Windows could not start because the following file is missing or corrupt: Isapnp.sys" error message at startup"
I have tried to repair it by booting off the original XP setup CD but when the computer starts up the CD is not read and the error message pops up again. Any suugetstion? THanks !
FYI: CD/DVD is powered up and tray will open and close.

To boot off the CD, you need to change the boot order in the BIOS. Tap the delete key on startup to get into the BIOS. Then change the first boot device to the CD drive. Press F10 to save and exit the BIOS. Then the next time you restart, it will tell you to 'press any key...' Do so at that time, and it will boot off the disc.
