The system is trying to boot through a network and you don't have one.

That network optiion is probably the last one in the list, the first being the CD drive and there's no bootable disk in there so the only other option is the hard disk. It couldn't boot from that so it goes on to the network option.

It's actually doing you a favour because it points to a serious hard disk problem.

When it's running properly, bring up a Command form by pressing the Windows key and R together and typing cmd into the run box and hitting the Enter key.

At the prompt in the black form, type
chkdsk c: /r
and hit Enter. The scan will take quite a long time depending on the size of the disk but the /r switch will try yto fix any disk errors it finds.

When it completes, it's a good time to back up all your personal files on to an external dissk.

You've probably worked out that it's OK to hit the Y key to that message.
