Most people that are capable of installing Linux (or some other Unixoid system) are probably capable of reinstalling GRUB (at least with a little help from a search engine of their choice). But if you try to get your parents to give Linux a try, because their laptop ends up infected with some virus every other month, this does not help. Which makes me think: What about dual-booting two Windows installations? This is probably a very rare scenario, especially with virtualization, but what if I was developing, say, device drivers and wanted to check my driver works both on, say, Windows 7 and 8/8.1? Does the Windows installer put my other Windows installation in the boot menu automatically? (Honest question, I have never tried this and probably never will.)
