Hi
Well that's better, if you really did get that message then it could mean that the hard drives has actually failed.
Do you have a lot of data that you can't lose on the computer?
Do you have any recovery media, or backups?
What kind of computer is it?
Does it have a recovery partition?
When you try to boot what happens, how far does it get, and does it just stop loading and not display any error message?
Does it prompt you to do a repair when you turn it on?
