Chapter 8. Advanced configuration While it is important to protect files, data, and settings that are on the hard disk or on the solid state drive, you may also need to install a new operating system, install new device drivers, update your system BIOS, or 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" on page 131 • "Installing device drivers" on page 135 • "BIOS Setup Utility" on page 138 • "Using system management" on page 149 Installing a new operating system If you install a new operating system in your computer, you need to install the Supplement files and ThinkPad device drivers for it at the same time. The necessary files are located in the following directories of your solid state drive or hard disk drive: • The Supplement files for the operating system supported are in the C:\SWTOOLS\OSFIXES directory. • The device drivers for the operating system supported are in the C:\SWTOOLS\DRIVERS directory. • The preloaded software applications are in the C:\SWTOOLS\APPS directory. Notes: • The process of installing the new operating system deletes all the data on your hard disk, including backups or images that were stored in a hidden folder by use of the Rescue and Recovery program. • If you cannot find the Supplement files, the device drivers, and application software you need on your hard disk drive, or if you want to receive updates and the latest information about them, refer to the ThinkPad Web site at: http://www.lenovo.com/support/site.wss/document.do?sitestyle=lenovo&lndocid=tpad-matrix Before you begin Before you install the operating system, do the following: • 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 sections you will be using. Go to the section for the operating system you are using: "Installing Windows 7" on page 132 "Installing Windows Vista" on page 132 "Installing Windows XP" on page 133 For the country or region code required in the installation, use one of the following: Country or region: Code China: SC Denmark: DK Finland: FI France: FR Germany: GR Italy: IT © Copyright Lenovo 2012 131
