BIOS Signature Verification Failed ERROR

[imtksmtmr]

Hi. I can't update BIOS.

I thought ' it is because of secure boot' and made it OFF.

I can't update through "HP PC Hardware Diagnostics Windows", "HP Firmware Update and Recovery" and "Update USB" all of them....

I have no idea completely....

Please Help me. Best Regards.

@imtksmtmr -- why are you trying to update the BIOS?  What is the possible "gain" ?

> I can't update through "HP PC Hardware Diagnostics Windows"  

Can you boot the computer, and press ESC, and then select "Enter BIOS SETUP mode" ?

From that mode, it might be possible to update the BIOS.

thanks for reply.

Actually, it's stable system.

so maybe I don't need to upgrade.

in the case of need to emergent update, I can't update now.

so if I could, I wanted to update.

in the long time, I have never seen just like this.

so I'm confused now.
