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'm becoming more and more convinced as I ponder these other responses and their fixes that the issue is some incompatible partition metadata residing on some usb drives. I'm thinking an alternate approach to the fix described in ronenfe's post of January 9, 2018 would be to use the diskpart "clean" command from Command Prompt or Power Shell with admin privileges and then do a quick format to FAT32 or NTFS.

    So in some cases at least it would seem that the problem has something to do with either the partition scheme or formatting subtleties. There might be some metadata present on some USB drives that the Media Creation Tool just doesn't like.

    Wow, it worked!

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