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.
• If your computer is equipped with both a storage drive and an M.2 solid-state drive, do not use the M.2
solid-state drive as a bootable device. The M.2 solid-state drive is used for "cache" function only.
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 75.
3. 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.
4. Change the boot priority order to boot your computer from the external DVD drive.
5. Press the F10 key to exit the ThinkPad Setup program.
6. Connect the external DVD drive to the computer and insert the Windows 7 operating system installation
DVD into the drive, and restart the computer.
7. Restore the C:\SWTOOLS directory that you backed up before installing the Windows 7 operating system.
8. Install the device drivers. See "Installing device drivers" on page 75.
9. Install the Windows 7 fix modules. You can find the Windows 7 fix modules in the C:\SWTOOLS\OSFIXES\
directory. For more information, go to the Microsoft Knowledge Base home page at:
