I tried to make bootable usb with nbdmifit, but i just can't do it. I'm stuck on that first step to make it bootable and usable. I can't find way to get to the point where i can start writing laptop serial number etc. I didn't find anywhere detailed tutorial from step one to the end.
Can somebody guide me how to extract DMI from mine not working bios? Then i can insert that part in the working bios that i downloaded here from the forum. BTW laptop that makes me headache is HP Probook 640 G2. I did found working bios, but just with bad, or missing DMI infos. How can i recognise DMI part...

I downloaded a theoretically working bios from this forum, there is a reaction because the keyboard lights up, the fan runs at full speed but there is still a problem because the screen is black. Could someone configure this file to my data? I would be very grateful.
