Windows Server 2008 R2 is supported by other versions except Foundation edition versions
The system must have two partitions, which must have Windows 7 boot_environmenet files and BCD storage

Up to 512 VHD files supported
Systems that are started from the VHD do not support system hibernation and over SMB sharing
