Can a Windows 10 ISO bootable USB be created without third party apps?

I want to create a Windows 10 bootable USB drive (or microSD in USB) through Ubuntu without thirdy party apps.

I tried dd, but it won't work, no boot.

I also tried formatting the device as FAT32 and copying the files, but that does not work anymore as one of the files from the ISO is larger than 4gb.

The answers on How can I create a Windows bootable USB stick using Ubuntu? all use third party apps or make me copy the files, which won't work anymore


A simple 'Do it yourself' method

A rather simple 'Do it yourself' method is described at the following links. You can create Windows install drives that work in UEFI mode as well as in BIOS mode,

  • help.ubuntu.com/community/Installation/iso2usb

  • help.ubuntu.com/community/Installation/iso2usb/diy

  • help.ubuntu.com/community/Installation/iso2usb/diy/windows-installer-for-big-files

    This method will work also with [new] versions of Windows 10 and Windows 11, where there is a file, install.wim, with a size > 4 GiB, so that the FAT32 file system cannot manage it, when extracted from the iso file. In this case there will be a small FAT32 partition and a bigger NTFS partition.


This 'Do it yourself' method is for you

  • if you have a Windows iso file that contains a file, install.wim, with a size > 4 GiB, or
  • if you don't like PPAs, or
  • if you want to 'Do it yourself' and understand the details

Implemented in mkusb version 12.5.6 and newer versions

This 'Do it yourself' method is implemented in mkusb-tow and available via mkusb version 12.5.6 (mkusb-dus) and mkusb-plug.

You get/update this new version of mkusb from the mkusb PPA via the following commands
