Some time ago I messed around and somehow managed to break my Ubuntu system so that it wouldn't boot. Instead of bothering to work out how to fix it I just re-installed (with a different version number) and kept my old /home partition. It all worked out of the box.
Yeah, what I meant was that I had my /home on / rather than on a separate partition, and managed to install a completely different linux distro anyway without losing it.
