Erro ao criar o pendrive inicializável

Question

Hoje eu tentei fazer um Pendrive inicializável com o Ubuntu 18.04.

Mas recebi um erro:

"DD image  
•   C:\Windows\explorer.exe (r)"  

E eu não sei o que fazer com isso.

Eu selecionei:

• MBR do esquema de partição para UEFI
• FAT32
• tamanho do cluster 8192b (era padrão)

Eu tenho 16gb GoodRam pendrive

Leia comentários para outros detalhes.
