Wondering how to fix Windows Media Creation Tool error 0x80042405 – 0xA001B?

A Media Creation Tool lets you download a Windows 10 installation file onto a flash drive (or DVD) that you can then use to reinstall Windows 10. It is extremely useful in the event something goes wrong with your computer. Furthermore, it is helpful to have a hard copy of the operating system.

Recently, several users reported that their screens display error 0x80042405 – 0xA001B when they attempt to create a bootable USB drive using Windows Media Creation Tool. We had a look into this issue and discovered that this issue is typically caused when the tool fails to format your USB drive. There is also a chance that a partitioning issue with the USB might be causing the issue. 

If you find yourself in a similar situation, you are in the right place because in this guide, we will walk you through the relevant troubleshooting steps in detail. 

Let’s get started!
