SSD Not booting

Hello:

I have
installed a new Samsung SSD 840 Pro and can not get it to boot on startup. I
cloned the drive with the Samsung Migration software without any problem. I changed
the setup to boot first from the SSD and then the old HDD. It passes the SSD
and boots from the old hDD everytime even though I have made every change that
I could see without any success. The SSD seems to be recognized in device
manager and the software was automatically downloaded after the first startup. Ideas
and advice would be greatly appreciated.
