grub rescue when trying to fix dualboot with Windows 8, what can I do? [duplicate]

I formatted the partition containing Ubuntu 13.04 running parallel with Windows 8, I then merged the partition disk into another disk and that is where the problem starts.

When I restart the computer and I get grub rescue.

I searched for solution on net they advised me to repair by booting with Windows CD, this resulted in another problem and now it's saying "operating system wasn't found " and I can not boot with Windows CD.

My OS is windows 8.

Please help me with a solution.
