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 145.
• 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.
• 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 150.
