I have installed Windows 10 and now I want to install Wubi... Is it possible?


From Wubi Guide:

Wubi is an officially supported installer for Windows XP, Vista and 7 only. Wubi does not work with Windows 8 default boot-loader. Thus at this point Wubi would not work on a new Windows 8 machine. You would be able to install, but not reboot into Ubuntu.

If you upgraded to Windows 8 and are using BIOS firmware, Wubi does work, but do not enable hybrid-sleep on Windows 8

Note that this applies to Windows 10 also.

  • @tamale I have to disagree. Wubi is still officially not supported. Thanks for pointing out the repo though. It wasn't there at the time of this post I guess.

In fact WUBI works with Windows 10. I had Ubuntu installed with WUBI to Windows 7. When I upgraded to Windows 10 I left it there, and it still works fine (Ubuntu 13.10).

I have not tried installing WUBI directlly on Windows 10, though.

    I tried it on a preinstalled Windows 10. It worked similar to my experience on a preinstalled Windows 8.1 see here. It is definitively possible, also if you have preinstalled system with UEFI. On my experience the commnunity supported versions work for beginners, too and the official Wubi version for 14.04 works for developers only.

Actually, there is a project in the works to allow you to use wubi with uefi bios PCs and I just used it on a brand new HP spectre x360 with windows 10 home to install ubuntu 16.10. It worked perfectly after I disabled secure boot in BIOS.

    Even if it works, this method is not officially supported.

No, you can't.

Wubi does not support either Windows 8 or Windows 10.

You can install Ubuntu as dual boot with Windows 10 the same way as with Windows 8.

This is the guide for it.

  • There is wubiuefi for windows 10. See my answer.

Wubi is the Windows Ubuntu Installer. Wubi installs Ubuntu inside a file within a windows partition, and thus it does not require CD burning or dedicated partitions, yet the installation is a dual boot setup identical to a normal installation.

For more information see: https://github.com/hakuna-m/wubiuefi/wiki

From https://github.com/hakuna-m/wubiuefi


  • make: builds wubi.exe, note that the first time you run it, you will have to install python inside of wine, this is performed automatically, just confirm all the default choices in the installation screens that will appear.
  • make runpy: runs wubi under wine directly from source
  • make runbin: builds wubi and runs the packaged binary under wine
  • make wubizip: creates a special zip file conatining python.exe and non byte compiled python files that is convenient for debugging purposes. Inside of Windows, unzip the archive, then run
    python.exe main.py --verbose. You can edit any file inside of ./lib.
  • make pot: generates a gettext template (po/wubi.pot)
  • make check_wine: creates the Wine environment if it doesn't exist.
  • make check_winboot: creates the environment for building and signing boot loaders if it doesn't exist.
  • make winboot: creates the boot loader files (old version)
  • make winboot2: creates the boot loader files (new version)
  • make clean: removes built files
  • make distclean: removes built files and environment

Code overview

  • src/winui: thin ctypes wrapper around win32 native graphical user interface
  • src/pylauncher: makes python code into an executable, the python script is examined and all the dependencies are added to an lzma archive, then an executable header is concatenated to the archive that decompresses it and runs the script using the python dll
  • src/wubi: the main wubi application, the code is split between backend and frontend, where each runs in its own thread. The two interact via a tasklist object, where the frontend usually runs a tasklist which is a set of backend tasks. Backends and frontends are platform specific. For now only the Windows platform is supported.
  • data: settings for wubi branding and customization
  • po: translations
  • bin: other binary files required at runtime (will be compiled at a later stage)

Wubi tasks

Wubi performs the following tasks

  • fetches information about the running system which will be used during installation
  • checks that the minimum installation requirements are met
  • retrieves required user information via a GUI
  • looks for available local CDs and ISO files
  • downloads the ISO if one is required, using bittorrent and an http download manager
  • checks the ISO/CD md5 sums and the md5 signature
  • extracts the kernel and initrd from the ISO
  • adds a new boot entry to the existing windows bootloader
  • prepares a preseed file to be used during the linux-side installation
  • allocates space for the virtual disk files

The actual installation is performed within linux after rebooting the machine.


  • edit the files in data as appropriate and build your image
  • you will need to provide an ISO that is similar to the Ubuntu ISO and in particular it must have .disk/info formatted like .disk/info in the Ubuntu ISO
  • you must provide a webserver with metalink file, metalink file md5 checksums and signatures for the md5 sums
  • add your signing key to data/trustedkeys.gpg
  • replace the generated dummy keys in .key with your signing keys for Secure Boot
  • on the linux side, the distribution must be capable of booting and rebooting off a loop file, perform an automatic installation and accept the special boot parameters that indicate the local preseed file and ISO image to boot from.

Here is the branch git clone, or download it compressed.

If you have Wubi installed on Windows 7 then yes. You can upgrade Windows 7 to 10 and you still gonna have Ubuntu on your computer.

    This does not answer the question. OP has installed Windows 10 and is not asking about an upgrade to Windows 10.
