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

    I just left the drive name empty, but turning off all unnecessary programs in the background and closing all open windows and not touching my computer while the process was running did the trick.

    Just putting the tool on USB didn't work, apparently you also need to close all other running programs.

    Trying to make a Windows 10 bootable USB stick. Used two different PC's, several USB sticks, formatted and reformatted.  Coping the Media Tool to the USB worked.

    Thanks much,  Chuck

    Tom, thanks for the info, it worked. Hopefully Microsoft works out the bug, it's very frustrating. Thanks again for the update fix around.
