@Pankaj81, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
This message usually appears when your HP laptop does not have an operating system installed or the system is unable to detect a bootable OS.

Here’s how you can resolve the issue with your laptop not booting properly:

Solution 1: Check Boot Order in BIOS

1. Turn on your laptop and press Esc repeatedly until the Startup Menu appears.
2. Press F10 to enter BIOS Setup.
3. Navigate to the Boot Options section.
4. Ensure the correct hard drive is set as the first boot device.
5. Save and exit by pressing F10.

If no hard drive is detected, your disk may be corrupted or disconnected.

Solution 2: Install Windows (or another OS)

If your laptop doesn’t have an operating system, follow these steps:

1. Create a Bootable USB Drive

• Use another computer to download the Windows 10/11 Media Creation Tool from the Microsoft website.
• Create a bootable USB using Rufus or the Media Creation Tool.

2. Install Windows

• Insert the bootable USB into your laptop.
• Turn it on and press Esc > F9 to open the boot menu.
• Select the USB drive and press Enter.
• Follow the on-screen instructions to install Windows.

I hope this helps. 

Take care and have a good day.
