Virtual Machine Not Starting

Hi All,

After creating my virtual machine, and I click start, I get the following errors:

An error occurred while attempting to start the selected virtual machines. 'Test Server' could not initialize.

I have already enabled the VT of the processor and Execute Disable Bit in the BIOS but each time I get the same problem. I have even removed the Hyper-V role and added it again, but no luck. Note that the environment is Windows Server 2008.

Can someone please tell me what I am missing?

Thanks
