elitebook 8460p will not boot from USB

[OldCyberian]

My elitebook 8460p refuses to boot from a USB thumb drive.  I've messed with the boot order, legacy boot option etc but no luck.  Possibly I need a bios upgrade.  Existing bios is ver F.03 but that might just be a red herring.

Hello @OldCyberian

Welcome to the HP Support forum. Let's skip the BIOS update for now and try other things first.

Please, read the official HP article about such issues you experience >> http://support.hp.com/us-en/document/c03736054

Article talks about CD/DVD but it is the same with USB devices. Artcile is applicable for devices with Windows 8/10 and Secure Boot/UEFI.

Something else that is not mentioned in the article - ensure your USB device is really bootable, the image stored there is not corrupted. If possible - redownload it and re-write it on the thumbdrive:

How to create bootable ISO on USB device >> http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows

When ready with the USB drive:

* Ensure Secure Boot is disabled.

* Ensure Legacy mode is enabled.

* Save the UEFI/BIOS changes.

Eventually, please, shutdown the computer using the power button.

Insert the USB thumdrive prepared previously

Power  on the PC.

As soon as you press the power-on button, immediately begin hitting the Esc button (like tap-tap-tap).

This should open a HP Startup Menu which may look similar to this one

Choose F9 to open Boot options. Select the thumb drive as boot option.

Follow the on-screen instructions to boot from this device/ install the OS / do your work / etc... 🙂

Hope this helps. Let me know if you face difficulties.

Thanks!!  My BIOS prompts/screens were quite different from the examples.  I never did see a direct reference to secure boot but one of the options seemed to turn it off.  I also discovered that not all USB drives are capable of booting (or so it seemes).

In my elitebook 8440p there is no Secure boot option (Bios 68CCU Ver.F.60). How can I turn it off? Moreover there are no any visible devise in boot order option.
