Question:  How Do You Boot To CD/DVD-ROM on an HP Laptop one time (e.g., to reformat it)?

Answer:

1. Turn off the laptop.
2. Turn on the laptop, and when it is booting up, press Escape.
3. Then choose option "F11" for System Recovery.
4. You'll see a screen for "Choose an option."
5. Select "Use a Device."
6. Then select "Internal CD/DVD-ROM Drive (UEFI)" (or the USB stick option).
7. When booting up you'll get a window that says "The selected boot device failed. Press <Enter> to Continue".  Press enter.
8. In the "Boot Manager" window, scroll to "Internal CD/DVD-ROM Drive" (or the USB stick option) and press enter

n.b.  You cannot merely move the .ISO file to a CD/DVD or USB stick.  It must be burned a special way (e.g., using Rufus).  There is a portable version of the software program called Rufus that does not require installation.  Some laptops only have CD ROMs and cannot read DVDs.  Having incorrect boot media (e.g., a DVD in a CD ROM or an .ISO merely placed on a USB stick), will result in the boot order skipping the device after powering on the laptop.
