well, you can get the cd from any computer stores(hopefully, you\'ve bought one), then the easiest way is to install a win 98 first on your system, then you can upgrade 98 --> win xp. Guess, the xp will does everything for you(i.e.you insert the cd to your computer, it\'ll autorun the cd and asks you if you want to upgrade or whatever..then just follow the screen)..
hope this solves your problem..any more problems, just post it again..
good luck
