I used to have Xubuntu 11.10 side-by-side with my Windows installation, installed via WUBI from Windows. After upgrading to Windows 10, however, this doesn't start any more, so I wanted to reinstall it.

However, I have noticed that WUBI is not included on the new 15.10 Xubuntu iso, and is also generally not supported any more.

Is there any way I can achieve what I had before, without partitioning my hard disk?
