Installing Windows 10 from a USB drive is a straightforward task that tech enthusiasts and novices alike can tackle. First, you need a USB drive with at least 8GB of space and a Windows 10 ISO file. Then, you’ll use a tool to create a bootable USB drive and change the boot order on your computer to start the installation process. Follow these simple steps, and you’ll have Windows 10 up and running in no time!
How to Install Windows 10 ISO from USB
In this guide, you’ll learn how to create a bootable USB drive with a Windows 10 ISO and install the operating system on your computer. These instructions will walk you through each step, ensuring you get it right the first time.
Step 1: Download the Windows 10 ISO
First, download the official Windows 10 ISO file from the Microsoft website.
Head over to Microsoft’s website where you can find the official download link for the Windows 10 ISO. Make sure you have a stable internet connection as the file size is quite large, and you’ll want to avoid any interruptions during the download process.
Step 2: Get a USB Drive Ready
Next, prepare a USB drive with at least 8GB of free space.
You’ll need a USB drive with sufficient storage capacity to hold the Windows 10 files. Make sure to back up any important data from the drive because the next steps will erase everything on it.
Step 3: Create a Bootable USB Drive
Use a tool like Rufus to make your USB drive bootable with the downloaded ISO.
Rufus is a free tool that simplifies the process of creating a bootable USB drive. Open Rufus, select your USB drive, and then choose the Windows 10 ISO file you downloaded. Click “Start” to begin the process, and wait for Rufus to finish its work.
Step 4: Change Boot Order
Access your computer’s BIOS settings to change the boot order, making the USB drive the primary boot device.
Restart your computer and enter the BIOS settings, usually by pressing a key like F2 or Delete during startup. Within the BIOS, find the Boot Order settings and move your USB drive to the top of the list. This ensures your computer will boot from the USB drive first.
Step 5: Install Windows 10
Finally, follow the on-screen instructions to install Windows 10 from the USB drive.
Once your computer boots from the USB, you’ll see the Windows Setup screen. Follow the prompts to install Windows 10, customizing the installation process as needed for your preferences. The installation might take some time, so be patient.
Once you’ve completed these steps, your computer will reboot, and Windows 10 will be installed. You’ll go through some initial setup screens to configure your preferences, like language and account settings. After that, your computer will boot into Windows 10, and you can start using it!
