Restoring Your Operating System
You can restore your operating system in the following ways:
•Microsoft® Windows® XP and Windows Vista® System Restore returns your computer to an earlier operating state without affecting data files. Use System Restore as the first solution for restoring your operating system and preserving data files.
•If you received an Operating System media with your computer, you can use it to restore your operating system. However, using the Operating System media also deletes all data on the hard drive. Use the media only if System Restore did not resolve your operating system problem.
