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?
