Restoring Your Operating System
Depending on your system configuration, you can restore your operating system in the following ways:
l For systems with the operating system installed on NVRAM module, the operating system can be re-imaged.
l Microsoft ® Windows System Restore (available only on computers that have hard drives and are running Windows Vista) 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 If you received the Operating System media with your computer, you can use it to restore your operating system. However, using the Operating System
media deletes all data on the hard drive. This option requires an external optical drive to run the media.
Re-imaging Operating Systems Installed on NVRAM
To restore, update, or install an operating system installed on the NVRAM module, refer to the re-imaging documentation for your computer at
support.dell.com.
