Windows 7 is still a popular operating system for many computer users, despite the introduction of newer versions such as Windows 8 and 10. If you want to install Windows 7 on a new computer or upgrade an existing system, you can use a bootable USB drive (pendrive) to easily install the OS. In this article, we will guide you through the step-by-step process of installing Windows 7 with a pendrive.

Step 1: Prepare the Pendrive
To start, you will need a minimum 4GB USB flash drive and a Windows 7 ISO file. Connect the USB flash drive to your computer and format it to FAT32. Once the formatting is complete, download and install the Windows USB/DVD Download Tool from the Microsoft website. This tool will help you create a bootable USB drive.

Step 2: Create Bootable USB Drive
Open the Windows USB/DVD Download Tool and follow the on-screen instructions to create a bootable USB drive with the Windows 7 ISO file. Select the ISO file and the USB drive, and let the tool do its work. This will take some time, so be patient.

Step 3: Set BIOS to Boot from USB Drive
Once the bootable USB drive is ready, you need to configure your computer’s BIOS to boot from the USB drive. Restart the computer and enter the BIOS setup by pressing the designated key (e.g. F2, F10, or Del) during the startup process. Once in the BIOS setup, navigate to the Boot menu and change the boot order to prioritize the USB drive. Save the changes and exit the BIOS.

Step 4: Install Windows 7
With the USB drive connected and the BIOS set up correctly, restart the computer. The Windows 7 installation process should start automatically. Follow the on-screen instructions to select your language, time and currency format, and keyboard or input method. Click “Install Now” to begin the installation.

Step 5: Enter Product Key and Select Installation Type
Enter your Windows 7 product key when prompted, or choose to skip this step and enter the key later. Next, select the installation type – either “Upgrade” for an existing Windows system, or “Custom (advanced)” to perform a clean installation on a new hard drive or partition.

Step 6: Choose Installation Location
If you selected “Custom (advanced)” in the previous step, you will be asked to choose a partition or hard drive where Windows 7 will be installed. Select the desired location and click “Next” to start the installation. If you are performing an upgrade, skip this step.

Step 7: Wait for Installation to Complete
The installation process will now begin. Windows 7 will copy files, install features, and update settings. This may take some time, so be patient and do not interrupt the installation process.

Step 8: Complete Setup
Once the installation is complete, your computer will restart. Follow the on-screen instructions to complete the setup of Windows 7, including creating a user account, setting up network and security settings, and customizing your preferences.

By following these step-by-step instructions, you can easily install Windows 7 using a bootable USB drive. Remember to back up your important data before installing a new operating system, and ensure you have the necessary drivers and software for your hardware and peripherals. With Windows 7 up and running, you can enjoy the familiar interface and functionality of this trusted operating system.
