Thanks Andrei for pointing this out, and also Werner to verify the solution
really works.

About the --force flag, it is required to proceed with block list installation.
As long as we have to support installation into partition boot record, ripping
it off unconditionally will make the scenario to fail. And I think it is a bit
weird to warn user about, for eg, you are going to install to extX partition
but it is unreliable ... We have been support that for years, maybe lilo, grub
0.96 and on ...

Therefore I close this as resolved feature. Hope this helps.

Thanks.
