i know i'm picking up on a bit dusty thread, but maybe you're still there. i've not had much luck with erunt - having loved it through the xp-years, i still set it up to autobackup, and also did some manual runs.
however, now twice i've tried to actually USE the backups it created, and both times i get a non-booting BSD system, which is not fun at all given that there's no real repair-install options unless your're alredy on your desktop.
so what could be going wrong when erunt does its restore?
and - for future reference - if erunt doesn't work, what WOULD? i've so far never succeeded with system restore, so my 1st inclination is to just keep it disabled.
