How do I uninstall Endless if I installed it alongside Windows?

This FAQ applies to version 3.0 or higher.

If you have used the Endless Installer for Windows, you can uninstall Endless OS to return your computer to a Windows-only system. You can directly uninstall Endless OS from Windows (preferred), or if needed, by booting your computer using an Endless USB Stick.


  • Removing the C:\endless folder without running the uninstall process will prevent your computer from turning on correctly. Do not do this without running the uninstall process described below first.
  • Removing Endless OS from your computer will remove all of the apps and files that you have installed, downloaded and created in Endless OS. Do not follow these steps if you have not backed up any important information.

Uninstall Endless OS from Windows (recommended):

  1. Start your computer up in Windows
  2. Search for “Add or remove programs” in the Start menu and run it.
  3. Find the Endless OS entry and click “Uninstall”.
  4. You will be prompted to remove Endless OS and erase all of your files and apps stored within Endless. If you are happy to proceed, select “Yes”. (Make sure you have backed up things you’d like to save, otherwise, they will be permanently deleted)
  5. The uninstall should complete quickly and give you a message saying whether or not it was successful.
  6. Your computer will now boot directly into Windows without showing the menu to select Endless OS.

Note: You can also find the uninstall program in C:\endless\endless-uninstaller.exe. If you have lost or erased the program, you can also download the latest endless-installer.exe and rename it to endless-uninstaller.exe.

Uninstall Endless OS using an Endless USB stick:

You can boot Endless OS from an Endless USB Stick and use the eos-uninstall-dualboot script as follows:

  • Start your computer from an Endless OS USB stick
  • Search for “Disks” on the desktop and press enter to launch the Disks tool. Find your computer’s hard disk drive on the left. Select it and note the device name in the title bar, for example: /dev/sda
  • Search for “Terminal” on the desktop and press enter.
  • Type “sudo eos-uninstall-dualboot /dev/sda”, ensuring /dev/sda matches the device name you saw earlier, and press enter. You will be prompted for your password.
  • The uninstallation process will continue and you can reboot your computer without the USB stick, and enter Windows directly.
  • If Windows starts correctly, without showing the Endless OS dual-boot menu, you can now safely delete the C:\endless folder.
