Hey there! @Eshu_1991,

This generally means the hard drive is not responding to a testing inquiry from the motherboard and provides pretty strong evidence the hard drive needs to be replaced. 

However, try the steps recommended below and check if it helps.

Perform a hard reset

Turn off the computer.
Remove the computer from any port replicator or docking station.
Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
Unplug the AC adapter from the computer.
Remove the battery from the battery compartment.
With the battery and power cord unplugged, press and hold the Power button for about 15 seconds to drain any residual electrical charge from the capacitors.
Insert the battery and plug the AC adapter back into the laptop, but do not connect any of the peripheral devices.
Press the Power button to turn on the computer.
The computer starts normally or a startup menu opens.
If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.
After Windows opens, reconnect each peripheral device that was disconnected, one device at a time, until all devices are reconnected.

Restore the BIOS settings to default.

Turn off the computer and wait five seconds.
Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
Press F10 to Save and Exit.
Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
Follow the prompts to restart your computer.

Lastly, try running a hard drive test from the system diagnostics page and check if the hard drive is functioning correctly.
