Okay, I was wondering what file Ubuntu sees in windows to know to do the option of install alongside windows? For some reason, when you update Windows 7 to Windows 10. Ubuntu still sees Windows 7 as the alongside install. But, when you do a clean install of 10. Ubuntu does not see Windows 10 at all. I want to do a clean install of Windows 10 and Ubuntu 14.04, but would like to drop the file it sees on C: Drive after windows install before I install Ubuntu. So, what file do I need to pluck from Windows now and move to the clean install to do this?
