使用说明

曾经用于系统盘的硬盘进行数据迁移后，盘内会存在EFI系统分区和恢复分区，默认情况下是无法在磁盘管理中进行删除的。

如果希望将这个盘以后作为数据盘使用，可以通过一些操作处理掉相关分区。

其实本质上就是重置分区ID后删除分区。

重置分区ID后删除分区的步骤：

第一步

#### 第二步

第三步选择要处理的系统盘

注意disk编号，慎重，这里千万不要选错磁盘。

第四步查看要处理的系统盘

通过命令查看 partition 可以看到当前的分区情况。

第五步选取分区重置主要分区、恢复分区以及保留的对应分区ID。

SET ID=ebd0a0a2-b9e5-4433-87c0-68b6b72699c7

这时候已经可以在磁盘管理里右键手动删除券来删除EFI分区了

第六步回到磁盘管理，原先 1T 硬盘现在就全部空间都释放出来了，新建一个新的简单卷即可。

完！
