Compute Node Deployment Issue (HPC 2008 R2 cluster) - Unable to Find winload.exe RRS feed

  • Question

  • We are currently having a problem deploying updated compute node templates on our 2008 R2 cluster (installation fails with the unable to find winload.exe upon node restart following OS install).

    The process that we used for generating our image was as follows:

    1. From a DVD deploy an preconfigured compute node image (Windows 2008 OS)
    2. Install HPC 2008 R2 Pack and add to the 2008 R2 cluster
    3. Use the capture node image in the cluster manager
    4. Create a bare metal template to deploy this image
    5. Successfully deploy image (via PXE) to original node plus 15 others
    6. Update the software installed on one of the nodes
    7. Use the capture node image in the cluster manger to capture this updated image
    8. Create a new bare metal template for this image
    9. Attempt to deploy image (via PXE) -> Fails

    When we reach step 9, the image is successfully copied to the target node and Windows is installed. However, upon reboot loading windows fails with the unable to find winload.exe error. If we use a WinPE disk, we can run bcdedit and give the following three commands, which fixes the boot information and allows windows to continue loading. However, that also apparently terminates the installation script  (have to now manually join it to the domain and add the HPC pack).

    • bcdedit /set {default} device partition=c:
    • bcdedit /set {default} osdevice partition=c:
    • bcdedit /set {bootmgr} device partition=c:

    If we attempt to redeploy the original image, that still works fine. The images are all a single HD partition. With respect to the network configuration we have both an enterprise network and a private network, with only the head node only attached to the enterprise network. We have also attempted recapturing the updated image, but that was no help either.

    Any ideas on how we can resolve this problem would be most appreciated.
