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 Factory Image Restore returns your hard
•
drive to the operating state it was in when
you purchased the computer. This procedure
permanently deletes all data on the hard
drive and removes any programs installed
after you received the computer. Use Dell
Factory Image Restore only if System
Restore did not resolve your operating
system problem.
If you received the • 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.
