Using MultiBoot
About the boot device order
As the computer starts, the system attempts to boot from enabled devices. The MultiBoot utility, which is
enabled at the factory, controls the order in which the system selects a boot device. Boot devices can include
optical drives, diskette drives, a network interface card (NIC), hard drives, and USB devices. Boot devices
contain bootable media or files that the computer needs to start and operate properly.
NOTE: Some boot devices must be enabled in Computer Setup before they can be included in the boot
order.
You can change the order in which the computer searches for a boot device by changing the boot order in
Computer Setup. You can also press esc while the “Press the ESC key for Startup Menu” message is displayed
at the bottom of the screen, and then press f9. Pressing f9 displays a menu that shows the current boot
devices and allows you to select a boot device. Or, you can use MultiBoot Express to set the computer to
prompt you for a boot location each time the computer turns on or restarts.
Choosing MultiBoot preferences
You can use MultiBoot in the following ways:
●
To set a new boot order that the computer uses each time it is turned on, by changing the boot order in
Computer Setup.
●
To dynamically choose the boot device, by pressing esc while the “Press the ESC key for Startup Menu”
message is displayed at the bottom of the screen, and then pressing f9 to enter the Boot Device Options
menu.
●
To use MultiBoot Express to set variable boot orders. This feature prompts you for a boot device each
time the computer is turned on or restarted.
Dynamically choosing a boot device using the f9 prompt
To dynamically choose a boot device for the current startup sequence, follow these steps:
1. Open the Select Boot Device menu by turning on or restarting the computer, and then pressing esc while
the “Press the ESC key for Startup Menu” message is displayed at the bottom of the screen.
2. Press f9.
3. Use a pointing device or the arrow keys to select a boot device, then press enter.
Using HP PC Hardware Diagnostics (UEFI) (select models only)
HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run
diagnostic tests to determine if the computer hardware is functioning properly. The tool runs outside of the
operating system to isolate hardware failures from issues that may be caused by the operating system or
other software components.
