Selecting a temporary startup device

Use this procedure to startup from any boot device.

Note: Not all CDs, hard disks, and diskettes are startable (bootable).

1.Turn off your computer.

2.Press and hold the F12 key then turn on your computer. When the Startup Device Menu displays, release the F12 key.

Note: If you are using a USB keyboard and the Startup Device Menu does not display using this method, press and release the F12 key repeatedly 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.

Changing the startup sequence

To view or change the primary or automatic power-on startup sequence, do the following:

1.Start the Setup Utility program (see “Starting the Setup Utility program” on page 25).

2.Select Startup.

3.Select Startup Sequence. See the information displayed on the right side of the screen.

4.Select the sequence of devices for the Primary Startup Sequence, the Automatic Startup Sequence, and the Error Startup Sequence.

5.Select Exit from the Setup Utility menu and then Save Settings.

If you have changed these settings and want to return to the default settings, select Load Default Settings on the Exit menu.

Exiting from the Setup Utility program

When you finish viewing or changing settings, press Esc to return to the Setup Utility program menu (you might have to press Esc several times). If you want to save the new settings, select Save Settings before you exit. Otherwise, your changes will not be saved.
