I was wondering how one can do bootable Windows 10 USB stick from Ubuntu. I have the file Win10_1909_EnglishInternational_x64.iso in the directory /home/jaakko/Downloads. But the startup disc creator gives OS Version Ubuntu. When I click other and select the Windows iso and double click the file, the Source disk image (.iso): shows still the file /home/jaakko/Download/ubuntu-18.04.3-desktop-amd64.iso. Is this a bug or why won't the disk creator show Windows 10?

    I have used woeusb in text mode successfully according to this link with current Windows 10 files (latest time a couple of weeks ago). -- The Ubuntu Startup Disk Creator uses the cloning method, and it does not work with Windows 10 iso files. Furthermore, that tool 'does not want to' work with iso files that are not Ubuntu iso files or look like Ubuntu iso files.

    I don't know what startup-disk-creator is, but is sound to specialised. You don't want to create a disk image. You just need to write the one that you have. Use a CD image burner. Feb 11, 2020 at 18:18
  • @ctrl-alt-delor. Maybe I did not explain clearly what I meant in my previous comment: The cloning method does not work with Windows 10 iso files to make a USB boot drive. -- If the user has a DVD drive and the iso file is small enough, a DVD image burner, for example k3b, is a good alternative. Otherwise booting from a USB pendrive is the remaining alternative, and woeusb is an extracting tool, that can do the job.

    @sudodus No your comment is clear, however I was not responding to it. I was responding to guest's question. It seems that you know that startup-disk-creator is not the correct tool. However the person that wrote the question does not. Feb 12, 2020 at 7:45
  • @ctrl-alt-delor, OK. Do you want that I remove my second (and third) comments?

The current situation with Ubuntu 20.04 LTS has changed since this question was asked, commented and answered.

woeusb is not yet working with this new version of Ubuntu, but there are alternatives.


1. Format the usb into MBR/DOS or GPT
2. Create FAT-partition (or for files > 4GB exFAT)
3. Use disk image mounter to mount .iso file
4. copy-paste all files of the mounted image onto usb device

use woeusb

Sorry for long answer instead of the link, but my reputation is still low.


It appears that the Windows 10 ISO image is also suitable for USB media without any changes. In that case, the steps are as follows:

  1. Insert the flash drive.
  2. Figure out what device the flash drive is. Don't guess here, since choosing the wrong device means you'll overwrite your hard drive. If the drive is mounted, run mount to see what the last line is, and pick the device portion of that (e.g., /dev/sdb if the line starts with something like /dev/sdb1). If it's not mounted, run dmesg (with sudo if necessary), scroll to the end, and find the entry for the device that starts with sd (sdb in the given example).
  3. If your device is listed in the mount output, unmount it by running sudo umount /dev/sdb1 (assuming that was what was listed).
  4. Run dd if=/home/jaakko/Downloads/Win10_1909_EnglishInternational_x64.iso of=/dev/sdb bs=1M, replacing /dev/sdb with the device you discovered in step 2 (without the digit on the end).
  5. Run sync and wait until it finishes.

That will write the data to disk, and then you can use it as a normal bootable flash drive.


I ended up simply installing Virtualbox from the Ubuntu store, installed a quick Windows 10 VM, and burned my ISO from there using Rufus.

That was the most frictionless method for me, while using a little detour.

Works like a charm, until woeusb dependency issues are resolved I can go to that native solution.

At the same time, you get to learn some Virtualbox, which might come in handy to any Ubuntu user.
