Does that help narrow down the problem?

OK, that was a mistake. The advice is bad. I do recall seeing the same thing, but I already knew to ignore it. Maybe you should register a bug that the text is misleading. At the very least, the 'install to partition' option should be buried within an 'Advanced users only' button.

So, basically what happened is when you installed grub to your windows partition it pooched windows.

Anyway, first try oldfred's advice - I think he said you may have to do it repeatedly.

If it still doesn't work, this link will do the trick...

I'm working on solving my problem still.
