@ddadafaffagagga, Welcome to HP Support Community. 

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

It sounds like your HP notebook is having trouble finding the operating system. Here are some steps you can try to resolve this issue:

Check Boot Order in BIOS:

• Restart your laptop and press the F10 key repeatedly to enter the BIOS setup utility.
• Navigate to the Boot Options or Boot Order.
• Ensure your hard drive or SSD is listed as the first boot device.
• Save and exit BIOS (usually F10 to save changes).

Perform a Hard Drive Test:

• Restart your laptop and press the F2 key repeatedly to open the HP Hardware Diagnostics menu.
• Select System Tests > Hard Drive Test.
• If the test fails, your hard drive may need to be replaced.

Use Automatic Repair:

• Create a Windows bootable USB using another computer (you can download the Windows Media Creation Tool from Microsoft's website).
• Boot your HP notebook from the USB: Insert the bootable USB drive, restart, and press F9 to access the Boot Menu. Select the USB drive as the boot device.
• Choose Repair your computer > Troubleshoot > Advanced options > Startup Repair.

Rebuild Boot Configuration:

• From the same Windows recovery USB, open Command Prompt (from Advanced Options).
• Type the following commands:

bootrec /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd

• Restart your PC and check if it boots normally.

Reinstall Windows (if all else fails):

• Boot from the Windows USB drive.
• Select Install Now, choose Custom Installation, and follow the on-screen instructions.
• If the installation fails to detect your hard drive, the drive may be corrupted and need replacement

I hope this helps. 

Take care and have a good day.
