You may be among those that purchased a new laptop recently and discovered that a lot of the softwares you wanted to install were simply not compartible with the vista that came along with it and would want to downgrade to xp without removing the original vista, then you really don't have to bother yourself.
Also most new HP do not have drivers for SATA harddisk, making it very difficult, if not impossible to install XP on them, however, If you have the time and a good internet speed you could do it by following the step-by-step procedure on http://www (dot) stopsolution (dot) (dot) com, however with a small fee I cud do it for u. I stay in ph. you can call me on 08062539746.
