Hi, BTW, I also had posted the Q @ http://stackoverflow.com/questions/42336175/why-meet-this-winload-exe-error-after-put-virtio-dirver-into-win7x64ultimate-iso.
My aim is making windows-virtio-drivers within win7x64ultimate.iso, so it can be used directly upon qemu-kvm with virtio bus, especially block devices and network interfaces. But it meets this error when boot&install from the modified iso. Here is my makeiso.win7x64.ps1: # TODO: simplify logics # By Bob # define variables $WAIKPEToolsPath="C:\Program Files\Windows AIK\Tools\PETools" $WIMInstallPath="C:\simple\install.wim" $WIMBootPath="C:\simple\boot.wim" $WindowsVirtIODriversPath="C:\simple\windows-virtio-drivers" $ImageInstallMountPath="C:\simple\mnt\install" $ImageBootMountPath="C:\simple\mnt\boot" cd $WAIKPEToolsPath pwd # then modify install.wim dism /get-wiminfo /wimfile:$WIMInstallPath # TODO: get $n from this output $n=4 while($n -ne 0) { $newdir=$ImageInstallMountPath+$n mkdir $newdir dism /mount-wim /wimfile:$WIMInstallPath /index:$n /mountdir:$newdir dism /image:$newdir /get-drivers dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\Balloon\w7\amd64\balloon.inf <# dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\NetKVM\w7\amd64\netkvm.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\pvpanic\w7\amd64\pvpanic.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\qemupciserial\qemupciserial.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\qxl\w7\amd64\qxl.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\vioinput\w7\amd64\vioinput.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\viorng\w7\amd64\viorng.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\vioscsi\w7\amd64\vioscsi.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\vioserial\w7\amd64\vioser.inf #> dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\viostor\w7\amd64\viostor.inf dism /image:$newdir /get-drivers dism /unmount-wim /mountdir:$newdir /commit # rmdir $newdir -Recurse -Force -Confirm:$false $n-- } # then modify boot.wim dism /get-wiminfo /wimfile:$WIMBootPath # TODO: get $n from this output $n=2 while($n -ne 0) { $newdir=$ImageBootMountPath+$n mkdir $newdir dism /mount-wim /wimfile:$WIMBootPath /index:$n /mountdir:$newdir dism /image:$newdir /get-drivers dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\Balloon\w7\amd64\balloon.inf <# dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\NetKVM\w7\amd64\netkvm.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\pvpanic\w7\amd64\pvpanic.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\qemupciserial\qemupciserial.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\qxl\w7\amd64\qxl.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\vioinput\w7\amd64\vioinput.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\viorng\w7\amd64\viorng.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\vioscsi\w7\amd64\vioscsi.inf dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\vioserial\w7\amd64\vioser.inf #> dism /image:$newdir /add-driver /driver:$WindowsVirtIODriversPath\viostor\w7\amd64\viostor.inf dism /image:$newdir /get-drivers dism /unmount-wim /mountdir:$newdir /commit # rmdir $newdir -Recurse -Force -Confirm:$false $n-- } # end Regards!
