Boot Sequence

This feature allows you to change the boot sequence for devices.

Boot Options

Floppy 

 

The computer attempts to boot from the floppy disk drive. If no operating 

system is on the drive, the computer generates an error message.

Hard Drive

 — The computer attempts to boot from the primary hard drive. If no 

operating system is on the drive, the computer generates an error message.

CD/DVD/CD-RW Drive

 — The computer attempts to boot from the optical drive. If 

no disc is in the drive, or if the disc is not bootable, the computer generates an error 
message.

USB Storage Device 

— Insert the memory device into a USB connector and 

restart the computer. When 

F12 Boot Options

 appear in the lower-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 ensure that 

your device is bootable, check the device documentation.

Network

 — The computer attempts to boot from the network. If no operating 

system is found on the network, the computer generates an error message.

Changing Boot Sequence for the Current Boot

You can use this feature to change the current boot sequence, for example, to boot from 
the optical drive to run Dell Diagnostics from the 

Drivers and Utilities

 disc. The previous 

boot sequence is restored at the next boot.

1

If you are booting from a USB device, connect the USB device to a USB connector.

2

Turn on (or restart) your computer.

3

When 

F2 Setup, F12 Boot Options 

appear in the lower-right corner of the 

screen, press <F12>.

 

NOTE: 

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.

The 

Boot Options

 appears, listing all available boot devices. 

4

On the 

Boot Options

 choose the device you want to boot from.

For example, if you are booting to a USB hard disk, highlight 

USB Hard Disk 

and 

press <Enter>.
