But as the original copy destroyed itself you should contact MS for a replacement Disk. It could very well come from a faulty batch which when heated up have air pockets which expand and cause the destruction of the CD. As it is XP Pro SP1 any CD of the same kind will do as the Product Keys are used for all the Cd's and you can install from one CD to numerous computers provided you use the Product Key applicable to the computer that you are loading.
MS should provide a replacement CD but may very well not replace the Drive if it suffered any damage. However failing that you can always make a "WORK" copy from a friends CD or any one that is from the same type and you will have no trouble in performing a reload or installing additional features.
