If you boot to recovery environment it lists the win7 installation that it sees. Is it listing one with (C:) at the end? So windows is on partition that is called C? Last time it was E!! Are you booting from dvd or using F8?

Yes! in recovery environment. windows 7 is listed and call c:\ partition!

i don't know what's happened. before E:\ called windows 7.

i boot with DVD Install windows home premium

Kaktussoft i'm wait for your replay.
