|As I said, it has nothing to do with the OS or hard drive. If the system is functioning normally, there should be a single "everything is OK" beep at startup. A series of beeps indicates a problem which can usually be determined based on the beep code. No beeps at all usually indicates a major hardware failure.|
I suggest you unplug the power cord, open the case, disconnect ALL the drives (floppy, optical, HDD) & unplug all external devices except for the monitor & keyboard. Then plug the power back in & see if the system will boot. If it still doesn't boot & there are no beeps, shutdown, remove ALL the RAM, then try booting again. A normal system will beep like mad if no RAM is installed. If there are still no beeps, your problem is probably with one of the "big 3" - motherboard, CPU, or power supply.
