That error typically means the hard disk is failing, but it can also be caused by something interfering with the boot process.

To verify the situation, run the Diagnostics routine. This will tell if the drive has failed or not.  From the screenshot shown, use the F2 option.  If that does not work, then:

To run the Diagnostics routine, Start tapping the Esc key BEFORE starting the PC and then press the start button.
Keep tapping the Esc key until a popup menu shows. Then pick Diagnostics from that popup menu, F2.
Report back with the results after running the Diagnostics routine. Also need the PC model number.

Here is a more complete list of things to do
