Example: if you assigned a letter V to the partition the command would be:

format V: /FS:FAT32

Não necessário: After the format you need to recreate the EFI directory structure with the command:

Não necessário: MD \EFI\Microsoft\Boot

Não necessário: Then change to the Boot directory with:

Não necessário: cd /d V:\EFI\Microsoft\Boot\

Não necessário: Then run:

Não necessário: bootrec /FixBoot

Não necessário: Finally run:

Não necessário: bcdboot c:\Windows /l en-us /s V: /f All

Type in the command:

bcdboot C:\windows /s V: /f UEFI (This replaces the above crossed out lines and works in Win 10 1709)
