How do you reinstal windwos xp pro without the cd?

i dont know of a way to reinstal it with out the cd but if your looking to fix a few problems that you may have encountered by changing a few things on the pc and your not trying to get a clean fresh instal then maybe you should look at checking out the system restore feature and try installing back to a date that was more suitable to your taste

hope that helps you some

If you copied your installation cab files, ie: the i386 directory, to your hard drive you could run setup from there.
