Technology: 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:

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.
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:
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)→
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)
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.
In my case the command goes like this: E:→cd win 7 sp1→
