I am looking into building a new pc, to complement a 6 month old store bought pc (a packard bell imedia 5094). I am fine with setting up the hardware, but how exactly would I install Windows xp onto the new hard disk, would I need to install ide controllers etc. before using a cd/dvd drive? Would windows auto install off a disk? And what security measures would stop me using an existing copy of windows xp or a copied disk? Thanks in advance to any help you could give a complete novice like me.
