Boot Sequence

This feature allows you to change the boot sequence for the bootable devices installed on your computer.

Option Settings

Diskette Drive — The computer attempts to boot from the floppy drive. If the floppy disk in the drive is not bootable, if no floppy disk is in the drive, or if

there is no floppy drive installed in the computer, the computer attempts to boot from the next bootable device in the boot sequence.

Hard Drive — The computer attempts to boot from the primary hard drive. If no operating system is on the drive, the computer attempts to boot from

the next bootable device in the boot sequence.

Optical Drive — The computer attempts to boot from the optical drive. If no optical media is in the drive, or if the media has no operating system, the

computer attempts to boot from the next bootable device in the boot sequence.

Integrated NIC — The computer attempts to boot from the integrated network adapter.

USB Device — Insert the memory device into a USB port and restart the computer. When F12 = Boot Menu appears in the upper-right corner of the

screen, press <F12>. The BIOS detects the device and adds the USB flash option to the boot menu.

Disabled — Disables the particular boot device. The computer attempts to boot from the next bootable device in the boot sequence.

NOTE:

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

NOTE:

An error message is generated only after the computer attempts to boot from every device in the boot sequence and no operating system is

found.

Changing Boot Sequence for the Current Boot

You can use this feature, for example, to tell the computer to boot from the CD drive so that you can run the Dell Diagnostics on the Driver and Utilities media,

but you want the computer to boot from the hard drive when the diagnostic tests are complete. You can also use this feature to restart your computer to a

USB device such as a floppy drive, memory key, or CD-RW drive.

NOTE:

If you are booting to a USB floppy drive, you must first set the floppy drive to OFF in system setup (see

1. If you are booting to a USB device, connect the USB device to a USB connector (see the Back View Features in your Setup Guide).

2. Turn on (or restart) your computer.

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

NOTE:

Keyboard failure may result when a key on the keyboard is held down 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.
