HP laptop ships with a recovery tool that will allow you to restore your operating system in its original state. The recovery tool does not require you to have the CD because all the data needed for the recovery is stored in a hidden partition on your hard drive. You can access that tool either from Windows or directly from the boot menu. You will be able to choose either to restore your computer to factory default settings and erase all the data on it or to salvage a damaged Windows operating system without compromising your data.
