Hi @Isra2, Welcome to HP Support Community. 

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

It looks like your computer isn't detecting the hard drive where Windows is installed. This usually happens due to one of the following reasons:

Possible Causes & Fixes

Check if the Hard Drive is Detected in BIOS

• Turn off your laptop and turn it back on.
• Immediately start pressing the F10 key (or Esc + F10) repeatedly to enter BIOS.
• Look for Storage Options / Boot Options and check if your hard drive is listed.
  • If the drive is missing: The hard drive might be loose, failing, or disconnected.
  • If the drive is present: There could be an issue with the boot sector or corrupted OS files.

Run HP Hardware Diagnostics

• Turn off your laptop.
• Turn it on and immediately start pressing F2 repeatedly.
• Select System Diagnostics > Hard Drive Test and run a Quick Test.
• If the test fails, your hard drive is likely faulty.

Reset Boot Order

• Enter BIOS (F10 at startup).
• Go to the Boot Order section and make sure the primary hard drive is set as the first boot device.
• Save changes and exit.

Repair the Boot Sector (Advanced Users)

If your hard drive is detected but still won’t boot, you can try repairing the boot sector:

1. Create a Windows 10/11 USB using the Microsoft Media Creation Tool.
2. Boot from the USB (press F9 at startup to open the boot menu).
3. Select Repair your computer > Troubleshoot > Advanced options > Command Prompt.
4. Type the following commands one by one and press Enter after each:
   bootrec /fixmbr
   bootrec /fixboot
   bootrec /scanos
   bootrec /rebuildbcd
    
5. Restart and check if the issue is resolved.

I hope this helps. 

Take care and have a good day.
