Boot Options
l 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.

You can use this feature to change the current boot sequence, for example, to boot from the CD/DVD drive to run the Dell Diagnostics on the Drivers and
Utilities media. On completion of diagnostic tests, the previous boot sequence is restored.
