Restoring Your Operating System

following ways:

earlier operating state without affecting data

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 delete all data on the hard drive
and remove 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 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.
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.
CAUTION: Take regular backups of your
data files. System Restore does not monitor
your data files or recover them.
