U盘安装系统所需工具：
1、WIN7系统ISO镜像一个
2、U盘一个（至少4GU盘，毒大的6合1需要8GU盘）
3、软碟通：ultraiso【下载地址：http://sq.newhua.com/softdown/614_2.htm，注册名:李明 注册码:509F-BA54-BBA6-73C5】
WIN7系统安装教程
首先下载安装软碟通，安装完成后用软碟通打开下载或自己制作的WIN7-ISO镜像，如下图
此WIN7-64位-旗舰版－SP1安装镜像小幻自己制作的，全球独一无二~
插上4G或者8GU盘，点选软碟通界面的“启动－写入磁盘映像”
单击“写入”
弹出警告，点击“是”（此操作会清楚U盘全部数据请事先备份好）
开始写入U盘
