Wubi (Windows-based Ubuntu Installer) is a tool developed by the Ubuntu project to let Windows users install and try Ubuntu without repartitioning their hard drive. It creates a large file on the Windows file system that acts as Ubuntu’s virtual disk and adds an entry to the Windows boot menu, allowing you to choose between Windows and Ubuntu at startup. Installation and removal are simple: you run the installer from Windows and can later uninstall Ubuntu through the standard Programs and Features panel, just like any other application.
Wubi was designed to make getting started with Ubuntu quick and low-risk, especially for newcomers. However, it is no longer maintained and is not supported for modern Ubuntu releases, particularly on systems using UEFI firmware or Windows 8 and later. For current setups, use the standard Ubuntu installer to create a proper partition, or consider alternatives such as a virtual machine or Windows Subsystem for Linux (WSL) on Windows 10/11.
Wubi is developed by Ubuntu. The most popular versions of this product among our users are: 1.0 and 19.1.
