Windows 7: Recovery disks will not load in new hard drive after crash

My hard drive crashed on my laptop. Before It crashed, It gave me a hard drive warning of imminent failure, and gave me an option to create recovery disks. I ended up creating 11 disks from the option. I installed the new hard drive and the BIOS reads that it will boot from the internal optical drive first. When I insert the first CD and start then computer, it continues to read "Operating system not found". When I look at the CD in another computer, it reads three files and one folder. The first file is an icon file which reads "Setup", the next is a "Media" bin file, and the last is an autorun setup information file. The last is a folder that contains various other backup files. My computer did not come with any copies of windows. Why is this not working?

Did you validate that the Recovery Disks after they were created? What was the result if any?

Is the replacement hard disk the same as the earlier one?
