Windows Boot from VHD

这个从Vista版本以后Windows的新增功能很实用，微软总算又减少了一个不良设计。

可以从VHD文件启动以后，一机多系统则变得灵活得多，目前我采用的系统方案如下：

C:\Windows\system32>bcdedit

Windows Boot Manager

--------------------

系统一共安装了4个操作系统，分别是：

1. Windows 7、64位，这是我日常使用的宿主操作系统
2. Windows 7、32位，这是我MM日常使用的操作系统
3. Windows 7、64位，这是我日常放在虚拟机中使用的操作系统
4. Windows 7、64位，这是磁盘上的操作系统

一般来说，我会启动OS1、然后通过vmware启动OS3。OS1作为宿主机运行，OS3则是虚拟机。如果OS3中毒或是被恶意软件篡改，则从事先备份的文件中恢复即可。如果要玩装在OS3上的游戏（或其他需要发挥计算机的性能的软件），则可以重新启动OS3，以物理机方式运行OS3。可以任意在虚拟机和物理机间切换，并且便于备份和恢复，这是操作系统可以安装在文件中带来的便利。
