Dual booting with two HDD

Hi everyone I need your help.

I have a Dell Dimension E251, I have the primary HDD running Windows 7, I recently installed a second HDD and installed Ubuntu 13.04 on it. Everytime I boot my computer I get and error message saying:

Error: no such device: 2b13b036-2205-4705-a89b-acd3817af143.
grub rescue>

What can I do to fix this and boot from my 2nd HDD
