some time ago i bought an SSD and since i had to reinstall windows i bought windows 8 with it. I kept windows 7 on my old HDD and i installed Windows 8 on the SSD. For some time i had both, and a dual boot screen would allow me to switch between them. But now i deleted the windows 7 partition and merged it to the partition where i keep all my files, movies etc. But i still have the dual boot screen showing up with windows 8 and windows 7 options. How can i remove the dual boot screen and just make it boot to windows 8?
