New Motherboard - System Board (00A) error BIOS code Startup

[DigitalTechRep]

I recently changed the motherboard and this message comes up. I tried changing the settings in the BIOS but they are greyed out. Pictures attached. How would I go about to fix the issue. I do have the previous motherboard at hand.

Welcome to HP Community

I have gone through your Post and would like to help

HP Computers use a customized BIOS. Since you replaced the Motherboard, the BIOS needs to be flashed and the System Information needs to be tattooed on the System BIOS again

 I suggest you contact HP Support in your Region for Service Options

1) Click on this link - www.hp.com/contacthp/ 
2) Select your product type below.
3) Enter the serial of your device. 
4) Select the country from the drop-down. 
5) Select the chat or get phone number options based on your preferences. 
6) Fill the web-form and proceed further.

Thank you
