Hard drive fried???

Hello,
I just bought a new Dell laptop. it's 2 weeks old. My dogs got into a bad fight so I jump up and put the laptop on the floor only I was 2 inches from the floor when I let go of it. After I finished with the dogs I came and sat back down , picked up the laptop and re-started it. I got the DELL screen then it asked for the installation disc. The laptop could not find the boot drive. My question is ...Is the hard drive fried? Or do I just need to put the installation disc in again. I did call Dell and gave them the error code and because I bought my laptop through a finance place I had to return the laptop to them and have them call DELL. Dell won't help my out until the laptop is paid off and changed in my name!
