    如何从U盘安装Windows 7

    Win7 RC的镜像想必已经人手一份了,今天说说如何从U盘安装WIN7,以节省手头光盘资源
     
    步骤一:准备U盘
    把容量在4GB以上的U盘插入计算机,在命令行运行下列命令,完成U盘的分区格式化。
    diskpart
    list disk
    select disk ? (?为list disk是显示的U盘编号,不要选错了把自己的C盘格式化掉)
    clean (清空U盘上的内容)
    create partition primary
    select partition 1
    active
    format fs=NTFS quick
    assign
    exit
     
    步骤二:复制安装文件
    使用虚拟光驱等工具,把Windows 7 beta或RC ISO中的全部文件复制到U盘上。
     
    步骤三:写入U盘启动信息
    在命令行执行如下的命令
    bootsect /nt60 X:
    其中bootsect位于ISO根目录的boot目录中,X是当前U盘在系统中的盘符。

    步骤四:使用U盘进行安装
    设置计算机从U盘启动,插入U盘即可进入跟光盘相同的安装界面。

    运行bootsect /nt60 C: 并复制光盘的boot 和efi 文件夹以及bootmgr到C:\下,新建sources文件夹并复制光盘sources\boot.wim至其中 此时计算机已经可以通过WinPE启动。从WinPE启动后,可以在安装界面按Shift-F10开启一个命令提示符窗口。在这里可以创建一个VHD并安装系统到VHD文件中,或者安装硬盘上的Win7甚至XP。其间可以格式化C:因为WinPE加载在内存中了。

    实践证明U盘的读取速度要远低于直接从DVD读取的速度

    另外,如果电脑配置强劲,使用wmware方式直接从硬盘导入iso,整个安装过程可能只需10分钟(5块10000转企业级硬盘、4核心处理器)
