1. 打开镜像文件，如下找到isolinux、boot文件夹里的cfg格式文件
同理，将boot文件夹下面的cfg文件打开，相应的中文改为英文即可
2. 使用查看代码的软件打开后将里面的中文部分改成英文：
将cfg格式文件中的中文改成对应的英文，对应的中英文如下：
启动Live系统 Boot Live system 启动系统安装器 Boot system installer 在安全图像模式下启动Live系统 Boot Live in safe graphics mode 在调试模式下启动Live系统 Boot Live in debug mode 按TAB键编辑 Press TAB key to edit 按'E'键编辑 Press 'E' key to edit
本人相应的文件修改后如下：
