mmm just a little Update here..
while digging more for the answer I found this http://www.tomshardware.com/forum/37304-63-drive-slows-windows-boot
IT helped me a lot
So the problem with "Starting Windows" hanging was, windows backup, system image.
if I dont make the system image it does not hang.
I also tried making a smaller partition of 2tb and didnt work either.
So I made another smaller partition of around 1tb and the system image didnt make "Starting Windows" hangs
so , win backup "System image" has an issue with hdd over 2tb .
thats the answer for my problem
