If you need to install or reinstall Windows 8.1, you can use the tools on this page to create your own installation media using either a USB flash drive or a DVD. This article will guide you through the steps to download Windows 8.1 bootable ISO file from Microsoft's official website.
Step 1: Prepare the Requirements
Before you begin, make sure you have:
An internet connection (internet service provider fees may apply).
Sufficient data storage available on a computer, USB or external drive for the download.
A blank USB or DVD (and DVD burner) with at least 4 GB of space if you want to create media. We recommend using a blank USB or blank DVD, because any content on it will be deleted.
Your Windows product key (xxxxx-xxxxx-xxxxx-xxxxx-xxxxx). If you will be installing the operating system for the first time, you will need your Windows product key. For more information about product keys and when they are required, visit this page.
Step 2: Download the Media Creation Tool
Use the media creation tool (aprx. 1.41 MB) to download Windows. This tool provides the best download experience for customers running Windows 7, 8.1 and 10. The tool includes:
File formats optimized for download speed.
Built-in media creation options for USBs and DVDs.
Optional conversion to ISO file format.
To download the media creation tool, visit this page and click on "Download Tool Now".
Step 3: Run the Media Creation Tool
After downloading the tool, run it and follow the instructions on the screen. You will be asked to select an edition of Windows 8.1, a language, and an architecture (32-bit or 64-bit). You can also choose to upgrade your current PC or create installation media for another PC.
If you choose to create installation media, you will be asked to select a media type (USB flash drive or ISO file). If you choose ISO file, you will need to burn it to a DVD later. You will also need to choose a location to save the ISO file.
The tool will then download the Windows 8.1 files and create the installation media for you. This may take several minutes depending on your internet speed and the size of the files.
Step 4: Use the Installation Media
Once the installation media is ready, you can use it to install or reinstall Windows 8.1 on your PC. To do so, follow these steps:
If you created a USB flash drive, insert it into the PC where you want to install Windows 8.1 and restart your PC.
If you created an ISO file, burn it to a DVD using a software like Windows USB/DVD Download Tool and insert it into the PC where you want to install Windows 8.1 and restart your PC.
If your PC does not boot from the installation media automatically, you may need to change the boot order in your BIOS settings. To do so, press a key (usually F2, F12, DEL or ESC) when your PC starts up and look for a menu that lets you choose the boot device.
Once your PC boots from the installation media, follow the instructions on the screen to complete the installation of Windows 8.1.
