Hi freind,

Before going for a new hard disk, try this. You may be lucky to get the proble solved.

1. Disconnect and reconnect the hard disk - power and data cable. Then restart.

2. Check whether HD is detected by Bios. Still not detecting some system files like ntldr.* may be missing.

3. Install another operating system in your PC.
