FDisk Error! ???

[sayaprayer]

My parents old PC is so full of crap I decided it would be best just to start with a fresh install. Its a HP Pavilion. When I put in the recovery CD and start it up, I get an error saying it can't detect the hard disk. It says I may need to run the FDisk. I have no clue what this means but it leaves me with a C:/ prompt. Anything I can do?

type FDISK and delete the windows partition
