Driver installation issues

Recommended Posts

I'm looking for confirmation on a theory. I am trying to run Windows Server 2008 R2 in a virtual machine, which is to say that the Disk and Network drivers are not included in the standard Win2k8R2 dvd. I intend to do full unattended installations inside the KVM Guests using the Virtio device drivers from RedHat.

The problem is that if I PXE boot WinPE, the Network card does not have an appropriate driver. If I install the drivers into the winpe.wim file ( with the instructions here http://technet.microsoft.com/en-us/library/dd744355%28WS.10%29.aspx ), the WinPE environment has drivers, but after the install, the OS is missing the drivers.

If I use a different virtual NIC (say e1000 from Intel), WinPE has the NIC driver, but not the disk driver. If I use the unattended XML file to point to the 'Out-of-Box Drivers' from WSIM,

        <component name="Microsoft-Windows-PnpCustomizationsWinPE" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<PathAndCredentials wcm:keyValue="ff025ef0" wcm:action="add">
<Path>Y:\images\win2k8r2_distribution_share\Out-of-Box Drivers</Path>

The Disk driver is not only used in WinPE, but it's also installed to the OS.

I would like to be able to add both drivers during the unattended process. Do I need to use DSIM to install the drivers into both winpe.wim and install.wim? Or is there another way to force the installer to make sure it installs drivers from the network share if the OS install image does not have them?

Ok, so my theory is garbage. I think the problem is with the viostor.sys, which means this is a Driver issue I would guess. It doesn't matter if I apply the driver to the winpe.wim or not, the viostor.sys driver is missing post-install.

I'll see if I can apply the driver to the install.wim.
