对应错误的分区表信息

$ sudo gdisk /dev/sdb
GPT fdisk (gdisk) version 1.0.3

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: present

Found valid MBR and GPT. Which do you want to use?
 1 - MBR
 2 - GPT
 3 - Create blank GPT

Your answer:

清除GPT、MBR之后，重新烧录一次镜像即可恢复。

$ sudo fdisk /dev/sdb

欢迎使用 fdisk (util-linux 2.31.1)。
更改将停留在内存中，直到您决定将更改写入磁盘。
使用写入命令前请三思。


命令(输入 m 获取帮助)： m

帮助：

  常规
   d   删除分区
   F   列出未分区的空闲区
   l   列出已知分区类型
   n   添加新分区
   p   打印分区表
   t   更改分区类型
   v   检查分区表
   i   打印某个分区的相关信息

  杂项
   m   打印此菜单
   x   更多功能(仅限专业人员)

  脚本
   I   从 sfdisk 脚本文件加载磁盘布局
   O   将磁盘布局转储为 sfdisk 脚本文件

  保存并退出
   w   将分区表写入磁盘并退出
   q   退出而不保存更改

  新建空磁盘标签
   g   新建一份 GPT 分区表
   G   新建一份空 GPT (IRIX) 分区表
   o   新建一份的空 DOS 分区表
   s   新建一份空 Sun 分区表


命令(输入 m 获取帮助)： o
创建了一个磁盘标识符为 0x19aa2586 的新 DOS 磁盘标签。
The old gpt signature will be removed by a write command.

命令(输入 m 获取帮助)： p

Disk /dev/sdb：58.2 GiB，62537072640 字节，122142720 个扇区
单元：扇区 / 1 * 512 = 512 字节
扇区大小(逻辑/物理)：512 字节 / 512 字节
I/O 大小(最小/最佳)：512 字节 / 512 字节
磁盘标签类型：dos
磁盘标识符：0x19aa2586

命令(输入 m 获取帮助)： w
分区表已调整。
将调用 ioctl() 来重新读分区表。
正在同步磁盘。

在linux系统中使用gdisk查看分析，如下是正常启动分区信息
$ sudo gdisk /dev/sdb
GPT fdisk (gdisk) version 1.0.3

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: not present


***************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format
in memory. THIS OPERATION IS POTENTIALLY DESTRUCTIVE! Exit by
typing 'q' if you don't want to convert your MBR partitions
to GPT format!

Command (? for help): q
