This only happens when I choose to boot into windows. The screen sort of hangs for about 20 seconds in a black screen with an underscore at the top left corner before even starting to boot into windows. I know its normal for this to happen for like 5 seconds tops, but this is happening for about 20 seconds and its dreadful trying to boot into Windows 7 because it takes so long. When windows is done starting up i don't even get any messages saying startup failed or something like that. This is so annoying that I even reinstalled everything but the same thing happened.
