Hp pavilion dv2000 internal error

Hello, EVERYONE
recently i have tried to reboot my hp pavilion dv2000 laptop and an internal error occured. During the system recovery it gets stuck at 7% and it wont move. I left it over night to see maybe it will move and nothing happen. Everytime i turn on my computer it wont load to windows and a boot manager setup pops up. i can continue or exit but all it does is restart the computer and the same thing happens It tells me a an internal error occured. The system cannot find the path specified.(0x80070003). Please help me!!!! I found out that the problem is that " a hard disk could not be found. If a hard dist is installed, it is not respnding." Please tell me how to fix this.
