Although this is a very useful tool and can help you a lot in certain situations, in some cases it causes more problems than it solves.
That’s the case with the 0x80042405 – 0xA001B error which appears when you want to create a bootable USB drive with Windows 10 v1903 update.
Here’s how one user describes it:
I download the tool to the desktop. I’m on an Admin account. I insert a 16GB thumb drive. I format it. I start the tool. I point it to the thumb drive. During the phase where the files are copied to the USB, I get some [..] error like this:
This is a pretty common error and many Windows 10 users are getting frustrated by it.
Can I solve the 0x80042405 – 0xA001B error easily?
There are a few solutions to get past the 0x80042405 – 0xA001B error, but first you should check out this quick guide where we covered a similar error with Media Creation tool.
Try those solutions and see if any of them work. If the issue is still present, there are a couple of other things that you could try.
Run the Media Creation tool in Elevated mode
You can do this by simply right-clicking on the executable file and selecting Run as administrator.When the UAC prompt appears, click OK and let the tool do its job.
- In the Windows search box type cmd, right-click the first result, and select Run as administrator.
- Run Diskpart then type list disk. Write down or remember the number of your USB drive.(for example, we’ll use Disk 1)
- Now type these commands one by one:
- select disk 2 <enter>
- convert mbr <enter>
- create partition primary <enter>
- format fs=fat32 quick <enter>
After doing this, your USB drive with the Windows 10 v1903 should work just fine and the 0x80042405 – 0xA001B error in Media Creation tool should be gone.
