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

    Hi tlz1,

    Glad you got it sorted. Regarding the New Simple Volume in Windows 10, I found that the first attempt to right-click and select New Simple Volume appears to do nothing. The window just disappears off the screen. But making a second attempt works.

    I put it down to strange Windows 10 behaviour!

    Hope this helps.

    I know there are alot of different ways that people have fixed this error. none of the ways seemed to work for me until I ran a SLOW format of the usb (using fat32) and ran the program as an admin. after that it worked just fine. and i even retested it but swapping the  usb from 64 bit win10 to having both 32 and 64 bit installed on the drive.
