    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 ###  Type              Size     Offset
  -------------  ----------------  -------  -------
  Partition 1    Primary             49 MB    64 KB
* Partition 2    System              98 MB    51 MB

Q: Qual é o "argumento" neste caso? E por que não é válido?

Esta não é a primeira vez que estou usando o Diskpart, já o usei várias vezes antes, sempre que havia partições de recuperação ocultas especiais em uma unidade de disco que não podiam ser removidas com ferramentas de disco convencionais como Diskmgmt.msc. Então, tenho certeza que acertei a sintaxe e estou fazendo tudo de acordo com as páginas de ajuda.

Estou trabalhando no Windows 8.1 e o UFD é um SanDisk Cruzer Blade de 4 GB, novo. Eu só tinha o PassMark Memtest86 instalado e isso é tudo que eu já usei. Eu tenho formatado o UFD hoje para remover o Memtest86 (formato rápido no Explorer), mas uma partição EFI oculta foi deixada no UFD. Veja a captura de tela abaixo.

    

Answer 1

Argumento inválido! Eu entendi agora.

Não há necessidade de anexar o comando ao número da partição quando a partição já estiver selecionada.

Em vez de:

select partition 2
delete partition 2 override

Use isto:

select partition 2
delete partition override

Tão simples quanto isso ...
