How to Format UEFI / EFI USB

 PROBLEM:- 

How to completely format a bootable USB flash drive because I found there's a partition on the flash drive named "UEFI_NTFS" (EFI > Boot & Rufus folders with .efi files inside) that cannot be formatted.

My other bootable USB with MBR partition can be fully formatted.
I still keep the Win10 iso file & Rufus if needed.

 

SOLUTION:-

          If the full format does not work then use the Diskpart command:

    Code:

Diskpart

list disk

select disk X

Clean all

Use the USB Disk number listed to replace X letter.
