Permanent Secure Boot Disable

HP Recommended
Z640 Workstation
Microsoft Windows 10 (64-bit)

Hi,

trying to disable Secure Boot and enable legacy mode to be able to boot from USB stick.

Doing that in the BIOS but as soon as I save and reboot, Secure Boot goes back to being enabled again: the BIOS setting change does not stick.

Please help!

Hi,

Try creating a supervisor password in the Bios (do not forget it) and perform the changes to secure boot. You can always remove the password later.

 

Hope it helps,

David

Hi David,

 

Did not work.

created the administrator password, and disable Secure Boot.

Once rebooted, secure boot is right back to being enabled.

 

Any other ideas?

Thank you.

Will it let you select the USB Stick when you press F9 while boot?

Nope, that's precisely why I'm trying to de-activate SecureBoot!

Hello

 

when you , in the BIOS setup , have disable SecureBoot , you save the configuration and the computer automatically reboot.

After you saved , you don't have to press any keys , just wait for a message appearing on the screen asking you to type a four digit number , the press Enter.

 

you a video showing it : How to Enable Legacy for Windows 7

 

hope this helps.

 

bye

 

At Power-on , press ESC to get the Start Menu or press F10 to enter BIOS Setting, then follow the video

That's the standard procedure.

Doesn't work for me.

As I said before, after reboot, SecureBoot goes back to being enabled.

HP "elite" customer service does not want to take up the challenge BTW.
