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 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.
