Thanks Tripredacus, your the best the command i needed was dism /mount-wim I succesfully mounted, added driver and unmountet the image but now i have a new problem... When i press F12 it automatic starts loading boot/x86/images/boot.wim (The one i injectet driver to) After a few seconds i can see the windows 7 install background, then it says "The file "autorun.dll" could not be loaded or is corrupt. Setup cannot continue. Error code is [0x7e] Maiby the pictures can help Again thanks for your help Tripredacus!
