Not only does install from a USB Drive removes the need for a DVD drive, but the install time is also greatly reduced. Read each step and perform it carefully so that you don’t mess things up. Our guide will have you rocking the new version of Windows in no time!

You will require a USB Drive with a minimum capacity of 4 GB.


Step 1: Format USB flash drive to NTFS format

  • In your Windows, go to Control panel -> system -> hardware -> Device manager.
  • Under the disk drives section, right-click on the USB storage drive and select Properties (As shown in the screenshot below).

  • Click on the Policies tab, select Optimize for performance. Click OK (As shown in the screenshot below).

  • Open your Windows Explorer, you should see the USB storage drive in the inventory. Right-click and select Format. Now Select NTFS from the drop-down bar. After that Click Start.


Step 2: Commands From CMD

  • On the Start menu, navigate to the command prompt entry. Right-click and select Run as administrator (As shown in the Screen Shot below).

Step 3: Creating bootable USB flash drive with win 7


  • Download Windows 7 iso (32-bit/64 bit) file to your desktop.
  • Download and install WinRAR.
  • Right-click on the Windows 7 iso file and select Extract to win-7. Extract the files to a folder (you can name the folder any name you want, but for illustration purpose, I named it win-7) on your desktop.


  • Now Open Your Command prompt (Not as administrator). In your command prompt, write following commands (also shown in screenshot below):

cd Desktop/win-7 (Change the destination to the folder that you have extracted)
cd boot
bootsect /nt60 X: ( where X is the drive letter of your USB drive )

  • Now, copy all the files from the Windows 7 folder to the USB flash drive.
