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.
CD Drive — The computer attempts to boot from the CD drive. If no CD is in the drive, or if the CD has no operating
system, the computer attempts to boot from the next bootable device in the boot sequence.
USB Flash 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.
NOTE: To boot to a USB device, the device must be bootable. To make sure 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 Dell ResourceCD, 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
System Setup
).
1. If you are booting to a USB device, connect the USB device to a USB connector (see Back View
).
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 extended periods 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 make sure that your device is bootable, check the
device documentation.
