HP recommends that you attempt to restore your system using the Restoring and recovery methods on page
100.
Creating a system restore
System Restore is available in Windows. The System Restore software can automatically or manually create
r
estore points, or snapshots, of the system les and settings on the computer at a particular point.
When you use System Restore, it returns your computer to its state at the time you made the restore point.
Your personal les and documents should not be aected.
Restoring and recovery methods
After you run the
rst method, test to see whether the issue still exists before you proceed to the next
method, which might now be unnecessary.
1. Run a Microsoft System Restore.
2. Run Reset this PC.
NOTE: The options Remove everything and then Fully clean the drive
can take several hours to
complete and leave no information on your computer. It is the safest way to reset your computer before
you recycle it.
3. Recover using HP Recovery media. For more information, see Recovering using HP Recovery media on
page 100.
For more information about the rst two methods, see the Get Help app:
Select the
Start button, select the Get Help app, and then enter the task you want to perform.
NOTE: You must be connected to the internet to access the Get Help app.
Recovering using HP Recovery media
You can use HP Recovery media to recover the original operating system and software programs that were
ins
talled at the factory. On select products, it can be created on a bootable USB ash drive using the HP Cloud
Recovery Download Tool.
For details, see
Using the HP Cloud Recovery Download Tool to create recovery media (select products only) on
page 99.
NOTE: If you cannot create recovery media yourself, contact support to obtain recovery discs. Go to
http://www.hp.com/support, select your country or region, and then follow the on-screen instructions.
To recover your system:
▲ Insert the HP Recovery media, and then restart the computer.
NOTE: HP recommends that you follow the Restoring and recovery methods on page 100 to restore your
c
omputer before you obtain and use the HP recovery discs. Using a recent backup can return your machine to
a working state sooner than using the HP recovery discs. After the system is restored, reinstalling all the
operating system software released since your initial purchase can be a lengthy process.
