EliteBook 840 doesn't boot from bootable usb with win 10

[AALex94]

I ve created a bootable usb with windows tool from the official site. (i've also tried with rufus)

After i insert the usb into the laptop it does not boot from it, nor display it as a boot option. I ve tried all sorts of combinations, nothing worked so far.

These are the settings that i ve seen most people use.

Is there anything else that i should do?

Hi:

The only suggestion I can offer is when you make the W10 USB installation flash drive, set the partition scheme as GPT, not MBR.

Leave everything else at the defaults.

To boot from the USB flash drive, have it in the USB port.

Turn on or restart the PC.

Immediately press/tap the ESC key to get the menu of options.

Select the F9 boot options menu and from that select the (U)EFI USB flash drive and press the Enter key.

I did that when i created the bootable usb with rufus. Doesn t work. The usb still not showing up in the list of bootable devices.

Can it be related to the fact that this laptop was a company laptop that didn  t allow plug in of usbs?

That could be possible. 

The only suggestion I can offer regarding that would be to set the BIOS to its defaults, save the settings and exit. 

That would remove any custom changes made to the BIOS.

Done that too. I did a reset to factory default, same thing🥲

@AALex94,

So, the bios was reset to the factory defaults, but the laptop still didn't boot from the USB and the laptop had a No Bootable Device Found error, correct? Reboot and go into F9, do you see "Boot from File"? If yes, click on it and do you see a huge string of characters and numbers? if yes, click on it and what do you see? That may show a location of boot files, and you may be able to manually boot into the USB from there. You can post their screen shots.

If you don't see, that means the laptop doesn't recognize the USB. Did you try other usb ports? Do you have another computer to see if the usb can boot on it? Or you can use a different USB disk and make a new Win10 installation from Microsoft.

there s noting on the boot from file option.

i ve tried other usb ports as well, same thing. 

i ve used the usb on my pc and it worked fine, it got recognized

unfortunately i didn t have another usb stick to try.

Is that Sandisk a factory-installed drive with Win10 on? If it is, it should've come with HP PC Diagnostics UEFI on it. If this tool runs ok, you can check USB ports for functionality. Remove a USB stick and start the laptop and go into F2 and choose Component Test and run the USB Port test. It'll ask you to connect a usb stick and test will begin. If the test passes, that means the usb port is functional. 

Are you trying to install Windows because of a no bootable device (3F0) error? The error can occur if the Sandisk is corrupted so you can run Storage test, too.
