After P2Ving a 2008 Server to Hyper-V, I received the following Winload.exe error (shown below) upon boot. It is Winload.exe’s job to load the OS Kernel…

To resolve, I used the steps found here, but since I love screenshots, I thought I’d share them so you can see the process/commands.

1. Boot the VM from the Server 2008 DVD and on the Install Now screen, select Repair your computer

2. On the Systems Recovery Options window, highlight the OS install to repair and then select Next.

3. When prompted to choose a recovery tool, select the Command Prompt.

4. Enter the commands below and reboot the server:

cd windows\system32
bcdedit /set {bootmgr} device boot
bcdedit /set {default} device boot
bcdedit /set {default} osdevice boot
