Wubiuefi is a Windows Installer for Ubuntu and it is a fork of official Wubi. There has been a growing number of users who have not been able to install Ubuntu with official versions. In the past the issues of official versions only affected newer UEFI systems but meanwhile the issues affect older systems with legacy BIOS, too.

As a result, a lot of users use Windows only, old Wubi versions with outdated Ubuntu versions (as a workaround for older systems where old Wubi versions work), or other Linux distros (because of missing their personal main advantage of Ubuntu comparing it with other distros) All these workarounds are not recommended by Ubuntu fans but some things happen even Ubuntu fans do not want it. So, it was time to create Wubiuefi.
