Problemer med Windows 7 installation: Update Boot Configuration

Hej,
Jeg prøver at installere Windows 7 på en fuldkommen formateret partition af C-drevet, hvor Windows Vista ligger på. Men når installationen næsten er færdig, efter den har genstartet efter at have kopieret og ekspanderet filerne, kommer en meddelelse op der siger noget i retning af "Windows could not update the computer's boot configuration". Jeg har prøvet EasyBCD, at installere nye drivere til mit chipset, at bytte om på boot konfigurationerne af min BIOS, men intet har virket. Sidste del af min setupact.log siger sådan:
