Changing Boot Sequence for the Current Boot

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.
