Chapter 3. Recovery system
When I purchased my computer, it included a copy of Windows. How can I
determine whether the copy of Windows is preinstalled by Lenovo?
On the outside of the sales package of your computer, you should find a
label containing configuration information for your computer. Check the
printed string next to OS. If it contains Windows or WIN, the copy of
Windows was preinstalled by Lenovo.
What is the Recovery Partition?
If your computer is preinstalled with any version of Windows 8 (8.1), the
storage device of your computer contains a Recovery Partition. This
partition contains the image file of the preinstalled Windows operating
system. In cases of system failure, you can use the Lenovo OneKey
Recovery system or the Windows Reset feature to restore the operating
system to its factory status.
Note: The Recovery Partition is not assigned a drive letter and cannot be accessed through
Windows File Explorer.
I uninstalled a preinstalled software, but there is no significant increase in the
free drive space.
The copy of Windows running on your computer may be WIMBoot-
enabled. For computers with WIMBoot-enabled Windows, the majority of
files needed for preinstalled software are installed on the Recovery
Partition and won't be deleted through normal uninstallation.
What happens if I attempt to delete or modify the Recovery Partition?
Attention:
• Do not delete or modify the Recovery Partition on a WIMBoot-enabled computer.
If the Recovery Partition is deleted or modified, you may not be able to
restore Windows to the factory status. For computer models on which
WIMBoot is enabled, deleting the Recovery Partition may cause Windows
to fail to start.
