I exported 2 virtual PCs from Hyper-V. and then imported them. I can't start one virtual machine that has Windows Server 2008 R2 installed. The machine starts, but then I only see a blinking underscore. I am trying to run these virtual PCs on Hyper-V 2008 R2 that is installed on bare metal.
Have you checked your boot order for the virtual machine? I have had this happen with bad ISO or image files and the virtual machine trying to boot from them. You can check the boot order from the Action menu for the Hyper-V Manager.
Load installation CD / DVD run repair and cmd and
saved my life....
