installing windows with windows CD

[wijcc]

I have NEC laptop which has Windows XP home edition on it. I have lost the windows CD that came with the laptop. It already has windows XP on it. Is there anyway of doing a fresh installation of the Windows XP with the CD.. from the files stored on the HDD?
Thanks in advance guys
