If you need to install or reinstall Windows 8.1, you can use the tool on this page to create your own installation media using either a USB flash drive or a DVD.
Before you begin, here are some things you’ll need:
• PC with a reliable Internet connection. The download is about 4 GB and the time it takes to download will vary based on your PC, your connection speed, and other factors.
• USB flash drive. Use a USB flash drive with at least 4 GB of space. We recommend using a drive with nothing on it because any content will be deleted.
• DVD. This requires a DVD burner on or connected to the PC you’re using to create the media, and a DVD player on the PC where you want to install Windows 8.1. Use a DVD with at least 4 GB of space. We recommend using a blank DVD, because any content on it will be deleted.
When you’re ready, connect your USB flash drive or insert the DVD, tap or click Create media, and then follow the instructions.
