Unable to set bios password, unable disable secure boot => ProOne 400 G3

[citmanagement]

We're struggling with new OOB ProOne 400 G3 AIO desktop PC's.

It's impossible to change anything in the BIOS if you enter it via the F9 bootmenu after you receive the error "select boot image did not authenticate"
If you'll go directly to the BIOS via F10 you're able to change the BIOS password or change the Secure Boot Settings...

This costs us a couple of hours to figure this out, so I hope this will help anyone else.

From which boot-device did the motherboard try to boot:

* USB memory-stick

* internal CD/DVD device

* external USB-connected CD/DVD device

* disk-drive

* floppy-disk

* network

Did you have a disk inside the CD/DVD drive?  If you remove it, and reboot, do you still get the error-message?

As you indicated, directly enter BIOS SETUP, and change the order of boot-devices, probably to move the disk-drive to the top of the list.

We tried to boot from DVD-drive, after the attempt the error appeared "selected boot image did not authenticate".

Now the system automaticly goes back to a selection menu, if we select BIOS setup in that menu and went to the Secure Boot Settings and change this to Legacy Support Enabled - Secure Boot Disabled => hit F10 to save and reboot the changes were NOT saved.

The only way that worked is do  a fresh restart and hit F10 to enter the BIOS, and make the same changes. Now after F10 save/reboot the systems asks to confirm the changes by enter a 4 digit code.

What is the content on the DVD media?

Is it a much-older version of Windows, e.g., Vista?

It was a bootable DVD with imaging software.

Then, disabling "secure boot" is the correct action.

Is there a newer version of that software available from the vendor of that software? It might be compatible with a "secure boot" system.

Unfortunately this was still the latest version 😞

I'm glad we figured it out how to change, it's just a bit strange that you're able to enter the BIOS but the settings aren't saved somehow.

Thanks for fast response! For now have a nice weekend 😉
