Dell Inspiron 1564 "Operating System Not Found" Problem

[balajistarrer]

When i Turn On my laptop , it Shows "Operating System Not Found" ,But If I restart
( by ctrl+alt+del ) everything goes fine...whenever i shutdown my lap and then switching it on it boots slowly and shows "Operating System Not Found" ,But when i restart ,everything goes fine..

What is the problem?

Make sure the hard disk is properly inserted in the laptop and has not come loose. You will need a screwdriver to remove the hard disk panel to check. That would be the first thing to check. Post back after you have done so and we will provide further steps if needed.

But if i restart no errors were shown and it boots up windows.. the hard disk is properly inserted ..
I checked that number of times..

In that case, run an HD Diagnostic using the diagnostic provided by the manufacturer. Both the steps for determining the manufacturer and the diagnostic links for the manufacturer are provided in that link.

Hope this may solve my problem..

You can also use a free program to identify all of your hardware.

Speccy Free System information Utility

Then you can use the link provided by writhziden to get the right hard drive testing app.

I saw that you posted that the Toshiba diagnostic tool did not work for your hard disk. It appears you deleted that post, but I still would like to make one suggestion. You can try SeaTools to at least scan the drive for errors. It will tell you if you have a good drive or not even if it cannot repair the problems. Run the short and long tests with SeaTools.
