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. 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.
2. Start the ThinkPad Setup program. See "Using the ThinkPad Setup program" on page 63.
3. Select Startup ➙ Boot to display the Boot Priority Order submenu.
4. Select the drive that contains the operating system installation program, for example, USB HDD.
Then press Esc.
5. 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.
6. Press the F10 key to exit the ThinkPad Setup program.
7. Insert the Windows 7 operating system installation DVD into the optical drive, and restart the computer.

• If you are starting 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
