Changing Boot Sequence for the Current Boot

For example, you can use this feature to boot your computer from the CD

drive so that you can run the Dell Diagnostics from the Driver and Utilities

media and then from the hard drive when the diagnostic tests are complete.

You can also use this feature to boot your computer to a USB device such as a

memory key, or optical drive.

1 If you are booting to a USB device, connect the USB device to a USB

connector.

2 Turn on (or restart) your computer.

3 When the DELL logo appears, press <F12> immediately.

NOTE:

for an extended period of time. To avoid possible keyboard failure, press and

release <F12> in even intervals until the Boot Device Menu appears.

If you wait too long and the operating system logo appears, continue to

wait until you see the Microsoft Windows desktop, then shut down your

computer and try again.

4 At the Boot Device Menu, use the up- and down-arrow keys or press the

appropriate number on the keyboard to highlight the device that is to be

used for the current boot only, and then press <Enter>.

For example, if you are booting to a USB memory key, highlight USB Flash

Device and press <Enter>.

NOTE:

To boot to a USB device, the device must be bootable. To ensure that your

device is bootable, check the device documentation.
