I have two WD Caviar black 1TB drives and lately complete software RAID1 by adding mirror through disk management on Windows 7 final. every was well and excellent pending I tried to restart and establish that Windows 7 won't boot. My computer is HP m9340f with IPIBL-LB mob. I have since detached 2nd HDD in mirror which does not solve problem.
