Windows 10 Media Creation Tool Error: 0x80042405 - 0xA001A

Greetings,

Recently, I have seen many people inquiring about this error regarding the Media Creation Tool. I myself got this error when I try to create a bootable USB drive (aka Create an Installable Media).

Here's what I tried:

Reformatting USB drive to FAT32

Deleting files

Tried to locate and run Setupprep.exe (I couldn't find this file in C:\$Windows.~BT\Sources or anywhere)

Change Startup Type of Update-Related Services (Startup Type: Manual -> Automatic)

Uninstalled and Reinstall Windows 10 Media Creation Tool

Made sure my USB is above 8Gb as instructed by the tool (it is 15Gb)

The Fix (for me at least):

1. Downloadthe Windows 10 Media Creation Tool directlyinto the USB drive that you want to use as a bootable device (meaning you download the Tool into the same USB you chose to use as an Installation Media). If you already downloaded the tool on your PC's Desktop, copy it into your USB.

2. Run the Tool directly from your USB, meaning you open File Explorer, locate the MediaCreationTool.exe in your USB and double-click to run it.

The installer should then create an Installation Media/Bootable USB.

Hope this helps!

Cheers,

Tom

    Wow, it worked!

    What worked? It's not clear what exactly you are referring to.

    The latest (v. 1803) Media Creation Tool executable (.exe) is 18,671 kb (18.6 mb). If yours is only 10mb something is wrong. I would download it again. The Media Creation Tool's purpose is to download the Windows 10 .iso file (which is a very large file) to your computer in a temporary folder, from there unpack the .iso file into the various Windows OS folders and files and install them on a flash drive in such a way that you can boot from it and begin the installation of Windows 10 on any computer that will run Windows 10. Yes, the flash drive installer is portable. It can be used on multiple computers. By the way, .iso (or just ISO) files are files that contain other files and folders compacted into one file. They are merely containers.

    Hope this helps.

    This made some things much clearer. Like where and when I press Run. 

    So I downloaded the creation media tool to a usb.  But it's only 10mb. Is this right? 

    So now in the same computer I then do the rest and then I am able to remove it from my big desktop to my small (where I need it) notebook and use it?
