Run clean. (Assigned by its Volume)

Once the thumb drive is clean, you can run create partition primary.

Now make the partition active by entering active

Then you need to set up the file system as Fat32 by running format fs=fat32 quick (quick, of course, specifies that you want to perform a quick format to speed up the process).

Entering the assign command gives the USB drive a drive letter, making it easy to access from Windows Explorer

Then you can copy everything from the Windows 7 installation DVD onto the USB key (a simple drag and drop will do).

Type exit in diskpart , that will go back to command window
