DELL D02U002 ユーザーズマニュアル

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.
