Restoring Your Operating System
You can restore your operating system in the following ways:
l 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.
l 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.
l If you received an Operating System disc with your computer, you can use it to restore your operating system. However, using the Operating System disc
also deletes all data on the hard drive. Use the disc only if System Restore did not resolve your operating system problem.
Using Microsoft Windows System Restore
The Windows operating systems provide a System Restore option which allows you to return your computer to an earlier operating state (without affecting
data files) if changes to the hardware, software, or other system settings have left the computer in an undesirable operating state. Any changes that System
Restore makes to your computer are completely reversible.
