Bootable usb pendrive using cmd

Creating a usb pendrive using command prompt is not hard, it is one of the most common ways to create a bootable usb.

      This method does not work if your operating sistem is windows xp or windows 8 , you cannot select the primary partition in comand prompt.

       You just need to follow these simple steps:

  1. First step is to obtain the windows files from somewhere and save them to a folder in your pc. You can rip a windows dvd , or if you have the iso image file you can open it with magic disc or daemon tools or even winrar , and you need to copy the whole content to a folder anywhere in your pc , you just need to make sure you know where it is located.
  2. Make sure your usb stick is inserted, go to start search cmd , right click the  file and select run as administrator. The command prompt will appear, now you need to write the following comands:
  3. diskpart→list disk→select disk 1(chose  the usb device, you will recognize it by its size)→clean(this will erase the usb)→create partition primary→select partition 1→active→format fs=ntfs(this will format the usb drive and will take 10-15 minutes)→Untitled 5
  4. After the format is done you have to continue writting  in command promt :  →assign(now you will notice that the usb drive changed its letter to (H): or (G))→exit(this command will exit the disk part function)
  5. Now you have to write the path to the executable file in your windows saved folder , make sure that in your windows folder you have the boot folder with the bootsect executable file.Untitled 8
  6. In my case the command goes like this:   E:→cd win 7 sp1→

           →cd boot→bootsect.exe/nt60 h:(h is the letter of the usb drive ,this comand will update the boot core)→exit (this will exit command prompt).
Untitled 6

  1. Now you have to copy all the files in the windows folder to your usb drive. Untitled 7
  2. ALL DONE. You can now restart your pc and boot from the usb hard drive.
