Unable for format Mini PC - X5 with Windows

I recently purchased a X5 Mini PC from the following site and was trying to have a clean install of Windows 10 instead of the pre-install copy with android.

During the installation process, I was thrown with an error stating that "Setup was unable to create a new system partition: Fix for Windows".

1. I have tried to work on this for a couple of nights along with this
   guide to use diskpart to pre-format and prepare the disk. But
   it didn't work, the same error still occurred.
   
2. Others suggest that it could be an UEFI locked issue and I should disable the secure boot option. However, the APTIO Setup Utility does not provide me with any option. I tried adding administrator password in security, hoping that it would enable the option as other suggest, but it failed to work.
   

Does anyone have similar experience or is familiar with BIOS and UEFI to lend a hand? Much appreciated.

 

Win 10 Pro upgrade using Win 8 Pro product key

I just bought a new computer running Win 10 Home. When I went to upgrade to Win 10 Pro using my Win 8 Pro product key from my old computer, the upgrade wouldn't activate.

Now I'm stuck with a bunch of error messages (mainly 0xC004C003) and am being told windows isn't activated. I can't seem to get my activated Win 10 Home back.

I don't have a product key for the Win 10 Home because it came pre-installed. There's no product code recorded on the packaging or labelling on the device.

So:

How do I either

• activate the Win Pro upgrade, or
• Get my activated Win 10 home back?
