recover preinstalled software. This information will help you handle your computer with proper care and
keep it in top working shape.

Installing a new operating system

In some situations, you might need to install a new operating system. This topic provides instructions on
how to install a new operating system.

Before you begin

Before you install the operating system, do the following:
• If you are going to install a new Windows 7 operating system, copy all the subdirectories and files in the
C:\SWTOOLS directory to a removable storage device, to avoid losing files during the installation.
• Print the instructions you will use. Go to the section for the operating system you are using:
– "Installing the Windows 7 operating system" on page 80
– "Installing the Windows 8 operating system or the Windows 8.1 operating system" on page 80
Notes:
– The UEFI BIOS features are supported on the Windows 7 operating system, the Windows 8 operating
system (64-bit) and the Windows 8.1 operating system.
– Be sure to set a preferred setting for the UEFI/Legacy Boot option in ThinkPad Setup.
– After installing the new operation system, you should not change the initial UEFI/Legacy Boot setting
in ThinkPad Setup. The UEFI/Legacy Boot setting must be the same as it was when the Windows
operating system image was installed. Otherwise, the new operating system will not boot properly.
