Bootable usb drive using command prompt .iso version

This is an updated version of the previous command promt post .

This version only requires the iso image file of the windows , a program to mount the image , and windows 7 or vista as operating sistem.

  1. The first step is to obtain a .iso image file of windows xp, vista, 7 , 8 is not suported in this method .Bootable USB Example
  2. Now you need to mount the .iso image file with magic disk , daemon tools or any other mounting program.Bootable USB
  3. The next step is to open the command promt with administrator rights. Go to start , in the search bar type cmd , and right click the cmd file and select run as administrator.
  4. In the cmd program you need to type the following commands: diskpart→list disk→select disk 1(disk 1 is my usb drive , you need to select your usb drive , you will recognize the usb drive by its size)→clean→create partition primary→select partition 1(or 2,3,4 depending on what number is your usb drive)→active→format fs=ntfs→(the formating process will take about 10-15 minutes).Create Bootable USB
  5. After the formatting process is done you will continue writting commands:→assign(this will usually change the usb drive letter to H or G)→exit(this will exit the disk part but not the cmd)→xcopy i:\*.* /s/e/f h:\→(i is the letter of the mounted .iso and h is the letter of the usb drive where you want to copy the files from i)→Untitled14
  6. This process will take another 10-15 minute.
  7. When the copping proces is done just type:→exit(this command will exit the cmd)Untitled15
  8. That was all , your usb drive is now bootable .
