Using the Operating System Media
Before You Begin
If you are considering reinstalling the Windows operating system to correct a problem with a
newly installed driver, first try using Windows Device Driver Rollback. See "Using Windows
Device Driver Rollback" on page 104. If Device Driver Rollback does not resolve the problem,
then use
System Restore
to return your operating system to the operating state it was in before
you installed the new device driver. See "Using Microsoft
Windows System Restore" on
page 106.
NOTICE: Before performing the installation, back up all data files on your primary hard drive. For
conventional hard drive configurations, the primary hard drive is the first drive detected by the computer.
