Ok, so I have two HDDs. I decided to reformat my Drive D today but encountered a strange problem. When I try boot up, it now tells me to choose two diff operating systems, it never did that before and now everything appears backwards. When I click to boot with my 1st HDD, the data had saved on it now appears on drive D. When I boot up with the 2nd HDD which would appear as Drive D on my 1nd HDD, data appears from drive C on it. What is going on..
