Hi everyone, had a question as to why the serial I put into windows 7 after a fresh install didn't work. My specs: GIGABYTE GA-EP45-UD3P Bios F10F Tutorials and files used coming from this thread. Application used: Award tools 1.31 Settings: Original bios=EP45UD3P.10f Slic 2.1 : HP Selected (HP.BIN) SLP : HP Selected (HP.TXT) Certificate I used (HP_2.1.XRM-MS) I created the bios file. Renamed the file EP45UD3P_SLIC.10f to EP45UD3P.10f. Then reset bios to load safe defaults and flashed my bios successfully. I then began to install Win 7 and picked the HP OEM SLP Key from this link. I picked from the ultimate paragraph and the HP key "MHFPT-8C8M2-V9488-FGM44-2C9T3". Then proceeded to install. When windows finished I checked the activation and it said that it was not valid "Error code 0xC004E003" . Mind you this is a fresh install and I have never used any boot loaders or even vista on this machine. Only thing I can figure is that I need to drop the certificate into window directory? The tutorial did not mention this so I am lost.
