Complete Guide: How to Reinstall Windows via USB with Rufus
This detailed guide will walk you through the entire process of reinstalling Windows on your computer, from downloading
the official ISO image to creating a bootable USB drive with the Rufus tool and, finally, installing the operating
system.
Requirements
Before you begin, make sure you have the following items:
- A computer with internet access to download the necessary files.
- A USB flash drive with at least 8 GB of storage capacity.
- The computer where Windows will be installed.
Part 1: Downloading the Windows ISO from os.click
The first step is to obtain the Windows ISO image. We will use the os.click website, which offers a simplified process
for downloading operating system ISOs.
1. Access the website: Open your browser and go to https://os.click/en.

needs. The site will guide you through each step.
6. Download: At the end of the process, a download link for the ISO image will be generated. Download the file and save
it to an easily accessible location on your computer.
Part 2: Creating the Bootable USB Drive with Rufus
With the ISO image in hand, the next step is to create a bootable USB drive using Rufus, a popular and reliable tool for
this purpose.
1. Download Rufus: Go to the official Rufus website at https://rufus.ie/en/ and download the latest version.
2. Run Rufus: Rufus is a portable application, so you don't need to install it. Just run the downloaded file.
3. Configure Rufus: Follow the steps below to configure Rufus correctly:
- Device: Insert your USB drive and select it from the device list.
- Boot selection: Click "SELECT" and choose the Windows ISO file you downloaded.
- Partition scheme: For modern computers, select GPT. For older computers, MBR may be the correct option.
- Target system: Generally, UEFI (non CSM) is the default option for GPT.
- File system: Keep NTFS.
- Cluster size: Keep the default.

displays the message "READY".
Part 3: Installing Windows
Now that you have a bootable USB drive, it's time to install Windows on the target computer.
1. Connect the USB drive: Connect the bootable USB drive to a USB port on the computer where Windows will be installed.
2. Access the BIOS/UEFI: Restart the computer and press the appropriate key to enter the BIOS/UEFI setup (usually Del,
F2, F10, or Esc). Consult your motherboard's manual for the correct key.
3. Change the boot order: In the BIOS/UEFI, navigate to the "Boot" section and change the boot order so that the USB
drive is the first device.
