Restoring Your Operating System
Operating System Reinstallation

Before You Begin

If you are considering reinstalling the
Microsoft® Windows® operating system to
correct a problem with a newly installed driver,
first try using Windows Device Driver Rollback.
To roll back the device driver:
Click 1. Start .
Right‑click 2. Computer.
Click 3. Properties→ Device Manager.
Right‑click the device for which the new 4.
driver was installed and click Properties.
Click the 5. Drivers tab→ Roll Back Driver.
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 49.
CAUTION: 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.
