Problem facing in installing winxp in hp laptop

hi,

i m facing a problem with windows XP installation in hp compaq laptop.

Whenever i try to install windows xp it shows the following message–

“Setup did not find any hard disk drives installed in your computer. Make sure any hard disk drives are powered on and properly connected to your computer, and that any disk-related hardware configuration is correct. This may involve running a manufacturer-supplied diagnostic or setup program. Setup cannot continue. To quit Setup, press F3. ”
