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

    OK, this was totally pissing me off but here is how *I* fixed it.

    Computer management

    Disk Administrator

    Remove the partion

    Create New Simple Volume

    Quick Format using FAT32 with all defaults

    reboot

    rerun the tool and create USB

    SUCCESS!

    I tried removing all partitions and reformatting and it didn't work for me. But Tom's workaround above did work.

    Yes, there are workarounds but Microsoft still needs to fix this issue. We shouldn't have to resort to workarounds. This has been an on again off again problem since the advent of the Media Creation Tool.
