在v819i贴吧看见有分享的img打包镜像文件，复制到u盘，连接平板自动安装报错。
virtual disk service error:
the operation is not support on removable media.
the system cannot open this device or file gpecified.
原因是里面有行代码：select disk "1", 一般默认平板硬盘是0，u盘是1. 理论上是应该选择：select disk "0",才会把系统安装在平板上（默认选择1后，导致把U盘都自动格式化了。）
如何修改呢？
解压压缩包到U盘后，有个scripts的文件夹。有点点击main.cmd,打开进行编辑。
