My friend is using Windows XP SP3. Few months ago, he had both Windows 7 and Windows XP SP3. He preferred XP over 7 and so removed Windows 7, just by formatting the drive that contained Windows 7. Now, whenever he starts his computer, he gets the option to choose between Windows 7 and Windows XP even when he doesn't have Windows 7 installed. He wants to get this problem solved. I tried to make everything normal but I could not open the Boot option when the computer starts. Please Help me.
