Things You Need to Prepare
Before guiding you through the process of how to create a Windows 8 bootable USB drive, you need to know some requirements and tips listed below:
- You need to prepare a 13 GB or larger USB drive. Also, it could be external USB hard drive.
- You need to prepare a Windows 8 installation disc or ISO file.
- The larger the USB drive is, the better the result will be. Meanwhile, certified USB 3.0 drives coming from vendors like IronKey, Kingston, Spyrus and others are recommended.
