Creating a bootable Windows 8 USB fails on a few percent

When I tried to create a bootable installation USB stick for Windows 8 by using Microsoft’s Windows 7 USB/DVD Download Tool, I found that the procedure failed at a few percent and gave some error that the USB stick could not be used to create the installation media.
After trying the same procedure on my two other laptops, I received the same error.

  • Open a command prompt.
  • Type “diskpart”.
  • Type “list disk” and note down the disk number of your USB drive.
  • Type “select disk 1”, where “1” is to be replaced by the disk number you wrote down in the previous step.
  • Type “clean”.
  • Type “create partition primary”.
  • Type “select partition 1”.
  • Type “active”.
  • Type “format fs=ntfs”.
    This may take some time, depending on the size and speed of the USB device you’re using.
  • Type “assign”.
  • Type “exit”.

Now, try creating the bootable installation USB stick for Windows 8 again Glimlach

Big fat note: The USB device you use must be at least 4GB!
