Open a terminal and type:

sudo nano /etc/grub.d/40_custom

Add the following line:

menuentry "Windows 7 (loader) (on /dev/sda1)" {
insmod part_msdos
insmod ntfs
set root='(hd0,msdos1)'
chainloader +1
}

by appropriately modifying the location of windows 7 in your computer. Then

sudo update-grub

Install ReFind, it will handle the Grub bootloader and the windows UEFI bootloader for you, and simply when you boot it will give you the choice of what to boot. http://sourceforge.net/projects/refind/
