If you are looking to install Windows 8 on your PC, the quickest and easiest way to do it is from a USB key. USB keys are much quicker for installing OS’s than using traditional DVD’s and are also easier to carry around with you. Once you’ve followed the guide below to creating a bootable copy of Windows 8 on a USB Drive, you can install it by going to the “Install from A USB” section of this post.


Just before we start, you are going to need a USB Drive with at least 4GB of storage space. Also, you can’t have any other files on the USB. If you do, the tool we are going to use is going to delete them all anyway so make sure you have a backup of any files you want to keep.

You will need to download Microsoft’s Windows USB/DVD Tool, then simply install the tool. Even though this tool is for Windows 7, it still works perfectly with Windows 8.


You will also need to make sure that you have an ISO image of Windows 8. At the moment, you can download the Windows 8 Consumer Preview ISO image from Microsoft for free. In the future, you will have to buy Windows 8 from Microsoft’s store to download the ISO image.
