So, the comp fails to start, and claims, "No Operating System Detected"

I tried Kaspersky on it, it ran it from the disc, so I know the optical drive works. I am at my wit's end.

It sounds like the drive has gone bad, or the boot sector is corrupt. What is the make and model of your computer? Can you get into the BIOS and check the boot order? Make sure the hard drive is selected as a boot option, and that the BIOS can detect it.

 

Can you get to the recovery console? On most computers, you press F8 immediately at startup and select the computer repair option. In the recovery console, try the startup repair option first. If that fails to fix it, you can try running chkdsk /r X: replacing X: with the letter used by your hard drive (usually c:).

 

If that doesn't work, you'll need to open the command prompt window in the recovery console and follow these steps to try to repair the master boot record. http://support.microsoft.com/kb/927392
