Problem Solved,

This problem occurs if the following conditions are true:. The computer has
two or more uninitialized hard disks.
. You started the computer by using Windows Vista installation media.


CAUSE
This problem occurs because Windows Vista cannot distinguish between
ambiguous hard disks.

In versions of Microsoft Windows Setup that are earlier than Windows Vista
Setup, hard disks are marked with distinct values to distinguish them.
However, this method of distinguishing hard disks is no longer supported
because of the potential for data corruption on hard disks.
