Notebook Operating System and Recovery

Hi,

Following the failure of the free upgrade process to Windows 10 on my Hp Pavilion x2 Detachable 10-n002ns, I have been trying to restore from a USB boot media (16Gb Sandisk USB key) created with the Windows Media Creation Tool (on another machine)

I have been unable to get the Hp Pavilion x2 Detachable 10-n002ns to boot from any other media at all:

I have tried:

• both DVD media and USB media, made with a variety of tools on both Windows (Windows Media Creation Tool, Rufus, LiLi) and Linux (Brasero, UNetBootIn, dd, Linux Mint USB Image Writer)
• Creating bootable media with settings for MBR and GPT partitions, for UEFI or regular BIOS.
• Booting to a variety of Ubuntu variant Live CDs (in order to check it wasn't just a problem with Windows)
• Secure Boot enabled (when booting Windows media) and Secure Boot disabled (when booting Linux)
• All variations of Boot Order in the BIOS.

As you can see in the image, there is no Legacy Boot option in the BIOS, and I have been unable to get any media to boot at all. Since the failed Win 10 update, the computer is now unusable.

Product Number is N3W80EQ#ABE

BIOS version is F.04 (I downloaded BIOS version F.05 from the HP website but was unable to get a FreeDOS bootable disk to be recognised)

I'm fairly sure there is a problem with the BIOS and UEFI boot. I note that this has been concluded elsewhere also. http://h30434.www3.hp.com/t5/Windows/Fresh-install-Win-8-1-Pro-into-Pavilion-X2-10-quot-32GB/td-p/48...

Please advise.
