Steps to create a bootable pendrive and install Windows 7 with Rufus.

Rufus is an installation wizard. Which offers the possibility of dispensing with a CD or DVD Windows for installation. This option is very practical, especially if your computer or laptop does not have a reader for this purpose.

The program will serve as a boot disk. That is, Windows will use it to start the system, instead of doing it from the installation on the main disk. To use this installation method we must first get:

A pen drive

It is recommended that it have a capacity at least 8 GB. It’s important to put attention on all previous files you have will be lost when installing the installer. For this reason it is better that you format the same.

The Rufus program

Being a free software, you can download it for free at Within the site we can find a portable version.

A Windows 7 .ISO file

You can find in here the way to download it in a simple way. It is possible that within your current system it appears as a compressed file (of the WinRar type). Don’t unzip it.

Once we have these three elements we can proceed with the installation. To do it correctly, follow these steps:

Start the Rufus program

When the download is complete, look in the related file for the Rufus program followed by the version number. It must have an extension .exe.


Insert the pendrive into the USB port

Note that, during system installation, memory should not be removed. Select the unit you just placed. You can do it in the program window, inside the section “Device”.

Choose the .ISO file

Press the button “To select” to choose the disk image (ISO) within the explorer. If you performed the steps properly, the Status bar will show “Prepared”.

Transfer begins

Press “Start” and the program will convert the files inside the .ISO into a boot file.

Warning window

Squeeze “To accept” in the pop-up window. The software warns you that the previous data on the pendrive will be erased. The transfer process may take a few minutes.

Remove the device

Once the previous step is finished, a green bar will appear with the word “Prepared”. It means that we can now eject the external device. To do this, go to the file explorer, right-click on the unit and choose “Expel”. After doing so, you can safely remove the pendrive.


By performing the previous steps, you will have converted your USB device in a Windows 7 installer.

Both the device and the input must be 2.0. We reiterate that you should not extract it until the entire process is finished.

Go to the tab “Boot Options”

It can also be found with the name “Boot”. In it you must tell the system to prioritize the start from the USB port.

Get out of the Bios

Press the key “Exit saving changes”

Push the button “Install Now”. After doing so, you will have to wait a few moments and the new operating system will already be running on your computer. Don’t worry if your computer restarts several times during the process.

Is it advisable to install Windows 7 now that its developers have removed support?

Choosing the 7 over its successors means depriving yourself of many new features. A modern interface, compatibility with new programs, voice assistants and system updates. The latter can leave our PC vulnerable.

Although there are always reasons force majeure to use Windows 7 as an operating system. If you have a somewhat old computer, it is likely that the new versions will not run properly or do not meet the minimum requirements. Another reason to reinstall or continue using this OS is compatibility with certain devices. It can be the case of CNC machinery, cutting plotter, or any device that has not updated its system and is only usable through version 7.

In short, it is always recommended, within the user’s possibilities, use the latest stable version of all software.
