text: If you already have a Win XP CD you don't need a new one.  It seems your hard disk might be damaged.\n\nRestart your PC and look if the screen shows a clue as to which key to press to enter BIOS setup (it varies from make to make, it's usually F1, F2 or Del).  Follow the menus, you should find an option to configure hard disks.  Let it find it automatically.  If it doesn',t you might need a new hard disk.
