Boot Sequence
This feature allows you to change the boot sequence for devices.
Boot Options
• 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.
• 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.
