Re-Instaling XP

Hi,

I bought a comp with XP home pre-installed, and never recieved any recovery or install disks. I know my windows key thanks to ‘cd key reader’. But with out these cds it seems impossible to re-install windows, there have been a number of problems with this install which prompts me to wish to install a fresh OS with sp2 etc streamlined in, and firefox etc instead of standard M$ browsers and media players. Is there anyway in creating this cd from the data on your hard drive?
