Chapter 5. Using the Setup Utility Selecting a startup device If your computer does not start up (boot) from a device such as the CD-ROM, diskette, or hard disk as expected, use one of the following procedures to select a startup device. Selecting a temporary startup device Use this procedure to startup from any boot device. Note: Not all CDs, hard disks, and diskettes are bootable. 1. Turn off your computer. 2. Press and hold the F12 key then turn on the computer. When the Startup Device Menu appears, release the F12 key. Note: If you are using a USB keyboard and the Startup Device Menu does not display using this method, repeatedly press and release the F12 key rather than leaving it pressed when turning on the computer. 3. Select the desired startup device from the Startup Device Menu and press Enter to begin. Note: Selecting a startup device from the Startup Device menu does not permanently change the startup sequence. Selecting or changing the startup device sequence To view or permanently change the configured startup device sequence, do the following: 1. Start the Setup Utility program (see Starting the Setup Utility program on page 16). 2. Select Start Up. 3. Select Quick Boot Mode, Num-lock or Startup Device Menu Prompt to set these devices. 4. Select Disabled or Enabled and press Enter. 5. Press ESC to return to Exit and select Save changes and Exit. If you have changed these settings and want to return to the default settings, select Load Optimal Defaults on the Setup Utility menu. 19
