Restoring Your Operating System
You can restore your operating system in the following ways:
• Microsoft 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. For
instructions, see "Using Microsoft Windows System Restore" on page 131.
• Dell PC Restore by Symantec restores your hard drive to the operating
state it was in when you purchased the computer. Dell PC Restore
permanently deletes all data on the hard drive and removes any
applications installed after you received the computer. Use PC Restore
only if System Restore did not resolve your operating system problem. For
instructions, see "Using Dell PC Restore by Symantec" on page 131.
• If you received
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. For instructions,
see "Using the Operating System Media" on page 134.
