+
+## 准备
+
+* U盘：容量为8GB或以上
+
+* 镜像：[AutolaborOS](http://www.autolabor.com.cn/download)
+
+* 烧录工具：[Etcher](https://www.balena.io/etcher/)
+
+  > 适用于Windows、macOS、Linux多平台开源烧录工具
+
+## 开始
+
+> 以Windows平台为例进行介绍，其他平台的操作方法大致相同。
+

+
+2.单击`Flash from file`（选择文件以烧录），然后选择先前下载的压缩镜像文件
+
+  > Flash from URL功能可能不稳定，不推荐使用该方式。
+
+  ![](imgs/windows_etcher_select_image.png)
+
+3.将待烧录的优盘插入电脑（若尚未插入）
+  > 如果 Windows 弹出如下提示对话框，则单击“Cancel”（取消）（请参阅[此处解释](https://github.com/balena-io/etcher/issues/2024)）：

+
+  > 如果在烧录过程中 Windows 弹出如下提示对话框，请单击“取消”。

+  ![](imgs/windows_etcher_insert_disk.png)
+
+7.烧录完成，从文件管理器中弹出U盘即可

+
+
+Etcher 烧录完成后，Windows 可能会提示你无法识别该U盘。此时只需单击“取消”，然后弹出U盘即可。
+
+## 常见问题
+
+* “Etcher报错，无法开始烧录？”
+
+  尝试使用管理员身份重新打开Etcher。
