You'll need to reinstall/update grub. I had the same issue after installing CentOS 6.4 on top of my Ubuntu 14.04. Following this post fix my problem:

    I am currently dual-booting Windows 8 and Ubuntu 14.04, and would like to get some familiarity with linux server admin. I plan to install CentOS and maybe host a small website or something. What will happen to grub after installing CentOS?

    I have an EFI system but the installation took place with a Live USB that wasn't created for EFI systems, I am booting Legacy. What does that change?

    Is Win8 in EFI mode while Ubuntu and addtional OS's are in legacy?

    Nope, both are legacy. I installed Win8 from a USB created using Win7 USB/DVD download tool.
