My story: I have win 7 installed in a 250gb hd. Couple days ago I bought a new hd and also install win 7 in there. I then format the old hd with the old os in disk management. But during start up it still ask me to choose which win 7 i want to boot on. The first one will boot up fine but if i choose the second one, it says "device inaccessible...". How do i get rid of that?
