Reinstallation
Before You Begin
If you are considering reinstalling the Microsoft

operating system to correct a
problem with a newly installed driver, first
try using Windows Device Driver Rollback. 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
“System Restore” on page 48.
CAUTION: Before performing the
installation, back up all data files on your
hard drive. For conventional hard drive
configurations, the hard drive is the first
drive detected by the computer.
Use Operating System Reinstallation disc only
as the last method to restore your operating
system.

items:

from which you ordered your computer,
or whether you requested the disc, the
