Windows Server 2008 R2 Hyper-V Virtual Machine failing to start after updates - black screen
Posted on 2014-12-14
I have restarted a Windows Server 2008 R2 Virtual Machine for windows updates yesterday. The updates installed as normal, but upon restarting, the VM will not come up. It starts to load windows for a second, and then goes to a black screen. Two other VM's running on this machine came back up fine.

If that is not the case, try the following command and reboot the guest:
(when booting to the windows cd it finds the main c: drive as D:, so thats why I used d: above)
Does anyone else have any other suggestions? Its an exchange server so it'll be a ton of work to rebuild.
