 First go to BIOS set up (restart your computer and hit F12 when the BIOS screen comes up), go to onboard devices and changed the SATA Operations from ACHSI (don't know how it got there) to the factory default setting ATA. Then I started up in "repair mode" (which was an option that was coming up when I tried to boot up before but never worked) – it went through a repair check and went to login screen.
Prior to finding this – I tried several things including start up from the Reinstallation disc, but nothing worked. I was ready to buy a new hard drive, but don't have to. Works fine!!

Hello Acke,

You will need to obtain a recovery CD from the following Dell Website: How To Request Backup CDs for Your Dell Computer

You can go ahead and download a Hard Drive diagnostic program that you will use to create a bootable CD to test your Hard Drive. Check the following page for details: Dell 32 Bit Diagnostics.

It is not a good sign for your laptop. It symbolizes that your hard drive may have bad sectors or it fails to run anymore. You can try the OS backup or recovery through bootable OS DVD.  If the error still unsolved, than you should consult with the manufacturer or repairer.

Well, BIOS configuration is not an easy work to do. When my Dell laptop started booting, I saw this error. But after configuring BIOS, I did not encounter any problems anymore. Everyone has given their own opinions and solutions. All solutions are good and helpful. But I want to thank especially Odom Vemus for giving the technique to configure the BIOS. Now, I have no more problems with my PC, and it runs as usual. Thank you very much.
