I have been reading many of the pervious post related to this error as it has now happened to me. One of the things that I came across that no one seemed to mention is this. If I leave a bootable cd/dvd in the drive, the "Press any key to boot from CD/DVD" message appears. If I let it time out, my laptop will boot into my Windows7 system. I still haven't figured out how to fix it. But I suspect a Bios issue rather than a hard drive issue. Any one else come across this?
