I am trying to use the Windows 10 Media Creation Tool to create a bootable USB flash drive but am getting an error message. It seems download the files successfully but fails part way through transferring the files to the USB drive.

The error message code I get is "Something went wrong … 0x80070456 – 0xA0019"

The steps I take are

  1. Run the program
  2. Accept the license conditions
  3. Choose "Create installation media for another PC"
  4. Language "English (United States)", Edition "Windows 10", Architecture "64-bit (x64)"
  5. Choose "USB flash drive"
  6. Choose the USB flash drive from the list

I am running Windows 10 Professional. The USB drive is 64Gb.

  • The real problem is the the USB device's formatting type . You need a FAT32 USB not an NTFS one. Indeed all the USB greater than 32GB NEED an NTFS system and is quite normal that the procedure doesn't work with them. You have to change in any case the system format of the USB in FAT32. ;)
