boot from ahci cd-rom : operating system not found

If you have a disc in the drive take it out and try again. Unfortunately it sounds like your hard drive has failed and it's looking to boot from the CD/DVD.

Do you know how to get into the BIOS or setup. When the logo comes up, on the bottom of the screen prompts will come up, (setup=F10). The key that links to the setup is what you need to press. In the BIOS, you need to check if your hard drive is detected. I am a hardware guy not a software guy but i try to help.

thanks for that, but when i am in the setup i have no idea how to check anything, there are 5 headings : main, advanced, security, boot and exit .. where do i go from here?
