HP Recommended
Product: HP Probook 640 G8
Operating System: Microsoft Windows 10 (64-bit)

I have bought a HP Probook 640 G8 Notebook Pc from Japan two months .Out of work needs, I uninstalled the Japanese version of the hp system, and then reinstalled the new windows10 system, and then I didn’t know what I did, and then the following red words appeared every time I turn on the Notebook PC :

System is booting in Manufacturing Program Mode :200

Warning: Your system is not fully configured. Please contact HP customeer support.

Warning: This BIOS is Not for Production Use.

Warning: This HP Endpoint Security Controller fimware is Not for Production Use.

Then I found the method in Google to upgrade the BIOS, but the BIOS firmware I downloaded from the official website for the corresponding model failed to upgrade in window10 and failed to upgrade with a U disk. The reason: "BIOS signature verification failed" was prompted and the upgrade failed. How to solve it, and how to solve these lines of red words?
