My computer and my dad's computer are both set like the above. Yet his computer is showing the boot menu when starting up, which only has Windows 7 on it. I used Easy BCD to rewrite the MBR, but that didn't make a difference. My computer doesn't show any boot menu. In addition to this issue, before the boot menu comes up, he gets a black screen with a DOS cursor blinking in the upper left corner. This screen will only go away if a key is pressed. So far I've seen that Shift and Space work. Letters didn't, odd, right? Anyway, yet still, another addition to this mystery, is when going to an Explorer window, say Computer for example, the address bar goes wonky. I've seen this on my grandma's computer before and it was caused by sticky keys. This keyboard is new though, so it doesn't have sticky keys yet. Pushing Shift also stops this from happening. Does anyone here have any ideas to what's caused these issues? I suspect they aren't linked to each other, but I'm not sure.
