ssd on latitude d531

I've got an old dell latitude d531.

I would like to install a SSD into it which earlyer had performed in a desktop. (Samsung 840EVO 250GB)

I backupped the original disk to the ssd and installed it into the laptop.

It fitted fine, but the laptop will not start up. It does not see a hard drive.
I tried to find adjustments in the bios, but can't find one.

Anyone has an idea how to get it working?
