here is the image i have pasted, i have got two drives on my system..
i booted in the other drive too, but it couldnt open that thru that too..
SO please help me.. now next thing i gonna do is boot in safe mode, or boot thru cd rom..
this may help..
but if i know how it encrypts the drive, Like if there is some script, or some file, which i can delete if i get access by booting thru CD ROM..
if anyone knows..
thanks for the reply mate..
