Hello, I have a problem I want to reinstall XP and I want to know how much space do I need to reinstall XP?

I think u need 1.3gb upto 1.5gb if u instal service pack

I'm not sure of the space for the inital install, however, with service pack 3 (SP3) and all updates as of today, it will be around 6 gig plus the size of your swap drive (virtual memory). So figure around 10 gig altogether. I wouldn't bother on anything less than a 20 gig drive and that's if you don't intend to install any large programs. One easy thing you can do after the initial install is to set your swap drive so that the minimum and maximum size are the same. This will prevent it from becoming fragmented and will give better overall performance in the long run.

"I have a problem I want to reinstall XP" What is the problem that's making you want to do the reinstall? "I want to know how much space do I need to reinstall XP?" Since you want to "re-install", that means you already have (or had) XP installed, right? So why are you asking? You know if will fit.
