  1. Plug-in your USB flash drive to USB port.
  2. Open Command Prompt with admin rights. Use any of the below methods to open Command Prompt.

Type cmd in Start menu

  1. You need to know about the USB drive a little bit. Type in the following commands in the command prompt:

First type DISKPART and hit enter to see the below message. (this opens the disk-partition manager)

Next type LIST DISK command and note down YOUR FLASH DRIVE'S Disk number (eg: Disk 1). BE CAREFUL NOT TO CHOOSE YOUR PRIMARY HARD-DRIVE.

  1. Next type all the below commands one by one. Here I assume that your disk drive no is "Disk 1".If you have Disk 2 as your USB flash drive then use Disk 2.Refer the above step to confirm it. So below are the commands you need to type and execute one by one:

SELECT DISK 1

CLEAN

CREATE PARTITION PRIMARY

SELECT PARTITION 1

ASSIGN

FORMAT FS=NTFS (Format process may take few minutes)

EXIT
