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 had the problem myself. Don't know why but after about the 5th time trying it just worked as it should. We should not have to go through these hoops to use Microsofts own tools. Shameful. I found this post after it finally just worked so I could try to find out why the error and use the methods for next time. Thanks for all the tips to try. This was the first time it did not work the first time on my laptop which I am admin of. Thank god for my easy to use chromebook that I now spend most of my time on.

    I found my USB stick was sleeping.  Go to Start, Run, Control Panel, and select Power Options.  Then go to 'Change When The Computer Sleeps'.  In this screen, click on the 'Change Advanced Power Settings', 'USB Settings', 'USB Selective Suspend Setting', and then change 'On Battery' and 'Plugged In' to Disabled.  This stopped my USB stick sleeping and I could then make the USB installation media.

    Great fix. [I did exactly as suggest, but it didn't work until I ran the tool from the USB as Administrator.]

    Thanks so much.
