It seems that it is good. Serg008 thank you. Is there any instructions on how to do it in the future in the new BIOS.
OK it took me a while but I finally got it working. I didn't know what I was doing wrong, but apparently I was using an old gigabyte certificate. Once I downloaded the new one from the link you provided, it worked! Thank you!
Thank you so much!!!! You need to modifify something in the anvanced section? I tried so hard without results and I was frustated...
