Windows 7 Crashes when Oversized Dynamic VHDs Are Used in Native Boot Scenarios.
With the advent of Windows 7 and Windows Server 2008 R2, Microsoft introduced native support for the virtualization technology. With it came native boot from VHD (virtual hard disk). Essentially, Windows 7 and Windows Server 2008 R2 can both boot as guest operating systems installed in a virtual machine as opposite to being deployed on the actual physical drive. However, Microsoft is warning customers using native-boot VHD that oversized dynamic virtual hard disks will crash the computer rather than launch the operating system.
