HP ZBook 15 G2 Mobile Workstation + motherboard change + boot issue grub rescue + memory issue

[Largo1972]

Hi all
I have to change my logic board "motherboard" in my ZBook 15 G2 Mobile Workstationlion after I changed, I had a message " grub rescue " in black screen but I find a solution to go in bios and change the boot option to legacy active after I install win 10 all fine but if I change back the setting in bios come back the same message from " grub rescue ", and the second issue after I boot my laptop coming out the same notification about memory is not compatible and the file system is bad, I run diagnostic but all fine I update bios all the driver but still the same, and also not showing the logicboard ID: numbers

Please any help will appreciate.
Thank you in advanceBoot screen 1Boot screen 2

Usually when a service technician change a mother board, they brand the new on with serial number and so on. I Think that part is missing here and that´s why you get the errors.

Yes is true, my self has been changed the motherboard, any possibility to brand the new motherboard or overwrite the EEPROM, any app or somehow overwrite the EEPROM.
