    THANK YOU!!! I was an idiot and marked my hdd partition as active and suffered from ‘BOOTMGT’ (I believe) is missing. Now I am back to running after marking it inactive through CMD on my Windows Install Disk. Thanks again! Was afraid there for a second until I saw your post. Total life saver. Literally! It would have taken me a life time to find all that software again! Just to let you know that you are still a helpin’ people.
