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

    Did not work. 16GB USB Fat32 format with exe moved over to the USB. 29% hang-up and then to 50% for the error code kick out. I need this tool to work on another PC that is in the Automatic Repair Loop! What a long day of all things not working. :-(

    Worked for me, thank you!

    Like some other comments...... I can't help but wonder why this fixes it.  It feels like a work around rather than a fix, but Hey Ho, at least it's a way to get to where you want to go!

    Used a 64GB USB

    Formatted the drive (FAT32)

    Copied the Windows 10 Media Creation Tool onto the USB

    Ran as Administrator

    Abracadabra.... it worked.

    Thanks for the suggestion.
