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

    to resolve the issue I was able to do it using two methods:

    1- format the USB drive and create GPT partition. I used easeUS to do that,

    2- Disable the secure boot in the bios.

    and RUN the tool as an administrator.

    Both solutions were successful and I was able to create the windows 10 1809 bootable USB with no errors.

    Good luck

    Here's the real solution:

    Don't use the Media Creation Tool to put the files on your USB drive; use it to download the ISO.

    Then download Rufus. (https://rufus.akeo.ie/)

    Once you have the ISO downloaded, run Rufus.

    In Rufus, select your device and the ISO file.

    (I used NTFS file system with default cluster size for the format options.)

    Click Start and let it do it's thing. (Took about 20 minutes for me.)

    That's it. You should be good to go.

    I tried doing this USB thing in the Media Creation Tool an obscene amount of times; I did probably everything mentioned in this thread (different file systems, formatting, changed service settings, etc). Nothing worked. Still kept getting the error. Then I just downloaded the ISO and used Rufus to put it on my flash drive. Worked perfectly on the first attempt.

    I hope this helps someone...
