HP Notebook PCs - Boot Device Options (F9)
This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008.
To access the Boot Device Options window, turn on the computer and immediately press the esc key to display the Startup Menu, and then press the F9 key.
This window presents the standard choices available in your BIOS for determining how your computer will attempt to boot the operating system on its next restart. Using the F9 option does not permanently change the way in which your computer attempts to start. It will only apply to the current startup process. For information about permanently altering your computer's boot order, please refer to HP Notebook PCs - BIOS Setup (F10).
The default settings for most computers are configured to boot first from the hard drive. The computer looks for the operating system, and tries to complete this startup process.
Some computers in business environments might be set up to boot from a specific location on the corporate network. This option is usually used for specific technical tasks, such as downloading operating system elements from a server.
If you are not on a network that supports booting from a server on that network, you will see an error message that references PXE. You will need to restart the computer and select a different boot option.
This option still exists in many systems, even though most computers no longer have floppy drives. If you have an external floppy drive available, with an operating system boot diskette, you can still use this option. If you do not have a floppy drive or diskette, it's best to disable this option entirely.
Optical Disc or USB drive
These options are usually enabled and moved to first in the boot order only when the operating system has failed, and you want to make sure that you can boot from an operating system disc or recovery disc.
These options may not appear in the Boot Device menu at all, unless such an optical disc reader or USB drive is enabled, plugged in, and holds a bootable media source.
Boot from EFI
You will rarely use this option. This option opens the file system and allows technicians from customer service or your IT management to run diagnostics.
