Chapter 6. Advanced configuration

This chapter provides information to help you further configure the computer:

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 start, print these instructions.

Attention: The process of installing a new operating system deletes all the data on your storage drive,

including the data that were stored in a hidden folder.

To install the Windows 7 operating system, do the following:

1. Ensure that you set the security chip to TPM 1.2. For more information, see "Setting the security

chip" on page 61.

2. Copy all the subfolders and files at C:\SWTOOLS to a removable storage device.

• The supplement files for the Windows 7 operating system are at C:\SWTOOLS\OSFIXES.

• The device drivers are at C:\SWTOOLS\DRIVERS.

• The preinstalled programs are at C:\SWTOOLS\APPS.

3. Start the ThinkPad Setup program. See "Using the ThinkPad Setup program" on page 70.

4. Select Startup ➙ Boot to display the Boot Priority Order submenu.

5. Select the drive that contains the operating system installation program, for example, USB HDD.

Then press Esc.

6. Select Startup ➙ UEFI/Legacy Boot. Then do one of the following:

• To install the Windows 7 (32-bit) operating system, select Legacy Only or Both.

• To install the Windows 7 (64-bit) operating system in Legacy mode, select Legacy Only.

• To install the Windows 7 (64-bit) operating system in UEFI mode, select UEFI Only.

Note: For computers with a non-volatile memory (NVM) Express drive, you can install the Windows

7 operating system onto the drive only in UEFI mode. In this case, ensure that you always select

UEFI Only.

7. Press F10 to save the settings and exit the ThinkPad Setup program.

8. Connect an external DVD drive to the computer, insert the Windows 7 operating system installation

DVD into the drive, and then restart the computer.

Notes:

• If you start the installation DVD image from an external USB device or if your computer has an NVM

Express drive installed, do additional configurations before you start. For more information, go to

• If an NVM Express drive is installed, additional drivers also are required. For more information, go to
