There is also some logic in Ubiquity that will copy Wubi.exe to the Windows
startup folder, when it finds 4 primary partitions already in use on an MBR
formatted disk. It asks "Install Ubuntu inside Windows?" as the first
option. e.g. http://askubuntu.com/q/536075/14916
When this happens, Wubi will run automatically the next time Windows starts
- in standalone mode - which means it will download the whole ISO and try
to install.

So it is *inaccurate* to say that Wubi is serving only as a "greeter" in
Windows. It is broken and needs to be fixed or removed.

Here is the Ubiquity code in case you're interested:
If you'll notice, the logic depends on whether Wubi.exe has been shipped on
the ISO or not. Remove Wubi and the logic is disabled.

Also I find it a bit rich for you to say "...if one wants to brick their
windows". Remember that Wubi.exe is signed and certified by Canonical. They
probably won't find it amusing that the team in charge of Wubi are making
comments like that. One would hope.

On that subject (on being in charge of Wubi), you do realise that there are
in fact patches supplied to fix Wubi? So if you wanted to you could just
promote them. For example:
https://code.launchpad.net/~hakuna-matata/wubi/upstart (merge requested in

If you need help with these I'm pretty sure hakuna-matata would be happy to
