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

    Hello, I have tried that and I still have the same error. I tried different USB key and different system

    Unfortunately the media creation tool for Windows 10 - 1709 is broken.

    Microsoft, please fix it!

    Hi,

    I think the problem is since the program library is somewhere on your hard drive in order for it to work properly you would have to create an environmental variable or adjust your registry manually.  These days the steps required are handled by a wrapper script (installation wizard). 

    Putting the program in the same space as the data solves the problem for any program if you always use the USB with the entire program library installed on it.  How did you create the tool?  There has been a lot of water under the bridge since I did mine but I don't remember it being update specific?

    This is the answer. 

    What I did was use disk part from a cmd prompt, clean the usb, then in control panel, initialize and format the usb stick, then run tool.
