Windows 7 new Feature support system boot directly from VHD

VHD http://www.aliyun.com/zixun/aggregation/16820.html ">native boot" is one of the new important features of Windows 7 and Windows Server 2008 R2, It enables the system to boot directly from the VHD.

I. Description

Windows 7 Enterprise or Ultimate version, not supported by other versions

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

If the VHD file type is dynamically expanded, you must ensure that the disk has sufficient disk space.

Up to 512 VHD files supported

Systems that are started from the VHD do not support system hibernation and over SMB sharing

The volume that holds the VHD file does not support Bitlock encryption, and the parent partition of the VHD file does not support volume Snaphot features

The VHD cannot be configured as a dynamic disk and also supports the establishment of software raid

Compared to physical hard drives, the VHD has no cache, so when writing data, the VHD hard disk differs from the physical hard drive, but the read performance is basically similar to the physical hard drive.
