Restoring Your Operating System
You can restore your operating system in the following ways:
• 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.
• Dell PC Restore by Symantec (available in Windows XP) and Dell Factory
Image Restore (available in Windows Vista) returns your hard drive to the
operating state it was in when you purchased the computer. Both
permanently delete all data on the hard drive and remove any programs
installed after you received the computer. Use Dell PC Restore or Dell
Factory Image Restore only if System Restore did not resolve your
operating system problem.
• Operating System installation media can be used to perform a reinstall of
your operating system. However, using the Operating System installation
media also deletes all data on the hard drive. Use the media only if System
Restore did not resolve your operating system problem.
