Hi @Vs720120 

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your screen is displaying "Please install an operating system on your hard disk," it typically means that the system cannot find a bootable operating system. Here are steps you can take to troubleshoot this issue:

1. Check BIOS Settings

• Restart your computer and enter the BIOS/UEFI setup (usually by pressing F2, F10, or Del during startup).
• Verify that your hard drive is recognized in the BIOS.
• Check the boot order to ensure that the hard drive is set as the first boot device.

2. Inspect Physical Connections

• Power off the computer and unplug it.
• Check the connections to the hard drive, ensuring that power and data cables are securely connected.
• If you have multiple drives, try disconnecting them and connecting just the main drive to see if it’s detected.

3. Run Hardware Diagnostics

• Many HP computers come with built-in diagnostics. Look for an option in the BIOS to run hardware tests, specifically for the hard drive.

4. Check for Drive Errors

• If you have a bootable USB or DVD with a recovery tool or installation media (like Windows), boot from it.
• Select the Repair your computer option.
• Choose Troubleshoot > Command Prompt and run:
• Replace C: with the appropriate drive letter if needed.

5. Rebuild Boot Configuration

• While booted from the installation media, go to Repair your computer > Troubleshoot > Command Prompt.
• Run the following commands:

6. Reinstall the Operating System

• If all else fails and you cannot recover the system, you may need to reinstall the operating system.
• Make sure to back up any important data if you have access to it.

7. Test the Hard Drive

• If you still encounter issues, it’s possible the hard drive has failed. Consider testing it in another system or using a drive diagnostic tool

I hope this helps.

Take care and have a good day.
