Restore issue with asus g51

I had to restore my older asus from the recovery disks that came with it ( I lost the 3 disks the computer prompted me to make on my own). However, I am having issues after I used the disks to restart. It not longer goes past the first part of the startup" when I try to start it from the HD it says there is a "disk read error" and prompts me to restart. When I try it with the disk in, it says "cdboot failed failed to find ntdlr". I have no idea what to do at this point.
Relevant information:
Asus g51vx
Running windows vista home premium.
Nvidia GeForce gtx 260m
Intel centrino.

I cannot find anything online to help me and even just a hint of what may be happening that I could look up would be incredibly helpful. The only thing I've found is a lot of threads saying the recovery disks for the asus don't work very well.......
