Without wanting to be pedantic from what is written it sounds like the PC is trying to boot froma CD/DVD that doesn't have a bootable disk in it or that bootable disk is corrupt. At no point does it mention trying to access teh HD.

Now this gets slightly complicated by the OP mentioning that they have tried doing a system recovery. What I would like to ask is that some people mistake system recovery from system restore. Are you sure you mean recovery? This usually involves completely re-installing teh Windows system and restting teh hard disk to its factory state. If you believe you have done a system restore reboot teh PC without any disks in teh drive and post teh results. It could be that you have inadvertantly tweaked teh BIOS and removed teh 2nd/3rd boot options that would normally drop back to HD if there is no CD/DVD in the drive.
