So make sure that all the virus guards and Malware guards are permanently turned off while the installation is complete.

After downloading Universal USB Installer, double click on it and run it. Agree to the license agreement and select create. Then as the first step, you will be asked to select the operating system you want to insert into the USB drive. Click on the dropdown box and scroll until you find Windows 7 installer. In the second step you need to give the location of your Windows 7 ISO file. Select browse and open the ISO file from your computer. Then as for step three, choose your USB drive from the dropdown box and select create and select yes. It will take several minutes to install Windows 7 into the USB drive.

After the installation is completed you are going to have a USB drive which have Windows 7 in it. Now you can plug the USB drive into any PC you wished to install Windows 7 and you can run the ISO file in it.

To install it first you must plug the USB and restart your PC. As soon as the screen appears, press the hotkey to open the boot options. Then select your USB drive as the boot device and press enter. Then it will load your ISO file and it will start installing Windows 7 into your PC.
