[SOLVED] Want to reinstall - what do I backup? After formatting a totally different primary partition on another drive that had held an older XP, for some reason Win 7 seems to think it's been dumped instead as it now won't load at all. And when I thought about it, I realised that for some reason I'd always had to select the Old XP drive in order to boot Win 7 - strange, but anyway. Win 7 is still on its own partition so I figure the best way to access it now is to reinstall. But I'd be keen to backup settings and the like to save me having to reinstall everything if that's possible? Where does Win 7 hold the most important things and for that matter, what are the most important files?!! (You can tell I've not ever used Vista perhaps, as I'm more used to the D&S of XP).
