I have installed HYPER V in 64 bit Windows 208 R2. I have made 3 partitions on the hard drive. I installed Windows 7 as one of the virtual OS and installed windows XP as another OS. My problems is when i start Windows 7 and then try to start the Windows XP, it gives error "The application encountered an error while attempting to change the state of WINXP".
What can be the problem, please advice. Attached screenshot of the error.
