我正在尝试使用 Diskpart 删除 UFD 上的分区。我通过提升的 CMD 提示符运行它。但问题是它报告我使用了无效参数。请参阅下面的日志。

Deletes the partition with focus.
Syntax: DELETE PARTITION [NOERR] [OVERRIDE]
NOERR For scripting only. When an error is encountered, DiskPart
continues to process commands as if the error did not occur.
Without the NOERR parameter, an error causes DiskPart to exit
with an error code.
OVERRIDE Enables DiskPart to delete any partition regardless of type.
Typically, DiskPart only permits you to delete known data
partitions.
You cannot delete the system partition, boot partition, or any partition
that contains the active paging file or crash dump (memory dump) filed.
A partition must be selected for this operation to succeed.
Partitions cannot be deleted from dynamic disks or created on dynamic
disks.
Example:
DELETE PARTITION
DISKPART> list partition

Partition 1 Primary 49 MB 64 KB
* Partition 2 System 98 MB 51 MB
DISKPART> delete partition 2 override

问：本案中的“论据”是什么？为什么它无效？
这不是我第一次使用 Diskpart，以前每当磁盘驱动器上有特殊的隐藏恢复分区而无法使用传统磁盘工具（如 Diskmgmt.msc）删除时，我都会使用它几次。因此，我很确定我的语法正确，并且我按照帮助页面做了所有事情。
我正在使用 Windows 8.1，UFD 是全新的 SanDisk Cruzer Blade 4 GB。我只在上面安装了 PassMark Memtest86，这就是我用它做的所有事情。我今天格式化了 UFD 以从中删除 Memtest86（在 Explorer 中快速格式化），但 UFD 上留下了一个隐藏的 EFI 分区。见下面的屏幕截图。
答案1
参数无效！我现在明白了。
当已经选定分区时，无需在命令中附加分区号。
代替：
select partition 2
delete partition 2 override
用这个：
select partition 2
delete partition override
就如此容易...
