Hi, I flashed bios and everythimg was ok. I install Win7, but when I try to install the certificate with: "slmgr.vbs -ilc c:\GIGABYTE-GBT-2.1.xrm-ms", windows give me one error: 0x80070057. Do you know if this error is frequent? Best regards.
Finally I found the problem. I used a certificate that didn't fit with the slic bios file. I used Award's tool and made a new bios file with asus slic. I used the correct certificate and it's working. Thanks Tito for the slic file
