Hi,

OK, so was that the ORIGINAL configuration? As in, was it originally set to Legacy disable / secure boot enable? Sometimes this will render the OS non bootable if you change it. Same with changing from Legacy to UEFI and vice versa.

If you run the F2 diags on the HDD does it pass?

Ok I did this but same error occured and yes this is original configuration...

When it goes to the first screen posted and suggests F2 to run the Diagnostics, What is the outcome for those tests?

[capriconuser]

When I press f2 this shows this.. and also I tried these options but none of them worked...

[TheOldMan]

So when you select Hard drive check and press enter, nothing happens?

And when you select "Exit" and press enter, it will exit?

[capriconuser]

When I click hard drive and then quick check.. then this shows message that " no hard drive installed please  check that the power and data cables are connected properly "

[TheOldMan]

That would indicate that either the hard drive has failed or became disconnected.  Since that would indicate needed to open the case and locate the hard drive, check that the cables are still connected, since you will be able to check those.  If they are intact, unplug and then reinstall the cables.  If it then indicates the same thing, then the hard drive needs to be replaced.

Sorry to say, looks like your HDD has died and is no longer being detected by the system. You'll need to get it replaced.
