Boot Sequence  
This feature allows you to change the boot sequence for devices. 
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 Drivers and Utilities CD, but 
you must set the computer to boot from the hard drive when the diagnostic tests are complete. 
1. Turn on (or restart) your computer.  
 
2. When the blue DELL logo appears, press <F2> immediately.  
 
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 Device Menu appears, listing all available boot devices. Each device has a number next to it.  
3. At the bottom of the menu, enter the number of the device that is to be used for the current boot only.  
 
Changing Boot Sequence for Future Boots 
1. Enter the system setup program.  
 
2. Use the arrow keys to highlight the Boot Sequence menu option and press <Enter> to access the pop-up menu.  
 
 
3. Press the up- and down-arrow keys to move through the list of devices.  
 
4. Press the spacebar to enable or disable a device (enabled devices have a checkmark).  
 
Press plus (+) or minus (–) to move a selected device up or down the list. 
Clearing Forgotten Passwords 
 
If you forget your user or setup password, you cannot operate your computer or change settings in the system setup program until you clear the forgotten 
password(s). 
 
1. Shut down the computer.
