My laptop has two hard drives, one 320GB HDD and a 30GB SSD. I installed Windows 8 on the HDD and Ubuntu on the SSD. However, after I installed Ubuntu, Windows 8 did not appear on the boot list. I tried boot-repair, but this didn't help.Here is the output of my fdisk -l:

I also tried sudo grub-update, but that also did nothing.
