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.

Installing the Windows 7 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 55.
2. Copy all the subdirectories and files in the C:\SWTOOLS directory to a removable storage device.
• The supplement files for the Windows 7 operating system are in the C:\SWTOOLS\OSFIXES directory.
• The device drivers are in the C:\SWTOOLS\DRIVERS directory.
• The preinstalled programs are in the C:\SWTOOLS\APPS directory.
3. Start the ThinkPad Setup program. See "Using the ThinkPad pointing device" on page 22.
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

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

non-volatile memory (NVM) Express drive installed, do additional configurations before you start. For
