# mkbootdisk

可建立目前系统的启动盘

## 补充说明

**mkbootdisk命令** 用来为当前运行的系统创建能够单独使用的系统引导软盘，以便在系统出现故障时能够启动操作进行适当的修复工作。

### 语法

```
mkbootdisk(选项)(参数)
```

### 选项

```
--device<设备>：指定设备；
--mkinitrdargs<参数>：设置mkinitrd的参数；
--noprompt：不会提示用户插入磁盘；
--verbose：执行时显示详细的信息；
--version：显示版本信息。
```

### 参数

内核：指定内核版本。

### 实例

```
mkbootdisk --device /dev/fd0 `uname -r`
```

其中，`uname -r`是目前Linux 系统所使用的核心版本，如果你有多个核心版本的话，你以可以直接输入核心版本。例如在这个网页中所使用的核心有两个版本，一个是2.2.12-20，另一个是2.2.18，若要以2.2.18设定开机的话，可以使用：

```
mkbootdisk --device /dev/fd0 2.2.18
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hezhiqiang.gitbook.io/linux/ming-ling/mkbootdisk.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
