Not dual boot. As to "anything but my data".. that's what I'm trying to
figure out.

Obviously my home directory, Also /opt has a few things there. I've got
a customized menu.lst. Along with several images for bootup. I don't
know where the file list of my extra repositories or associated keys
are, and I don't know if there is any other such "customized" data files
hanging around somewhere that I may want to keep.
