Hi @Devanshu_Bansal,

Welcome to The HP Support Community.  

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

I understand you are getting the "No bootable device -- insert boot disk and press any key" error typically indicates that your laptop is unable to find a bootable operating system on the hard drive. This could be due to incorrect boot settings, a disconnected or failing hard drive, or corrupted boot files. Here are steps to troubleshoot and resolve the issue:

Step 1: Check BIOS Boot Order

1. Access BIOS/UEFI:
   • Turn off the laptop.
   • Turn it back on and immediately press Esc repeatedly or F10 (depending on your model) to enter the BIOS/UEFI settings.
2. Verify Boot Device Order:
   • Navigate to the Boot or System Configuration tab.
   • Ensure the internal hard drive (or SSD) is set as the first boot device.
   • Save changes and exit (usually by pressing F10).

Step 2: Check Hard Drive Connection

1. Run Hardware Diagnostics:
   • Turn off the laptop.
   • Turn it on and press Esc repeatedly, then select F2 for diagnostics.
   • Run a hard drive diagnostic test to check for physical issues.
   • If the test fails, the hard drive/SSD may need replacement.
2. Check Hard Drive in BIOS:
   • In BIOS, confirm that the hard drive is detected under Storage or System Information. If not, it might be disconnected or failed.

Step 3: Repair the Bootloader

If the hard drive passes diagnostics and is detected:

1. Create a Bootable Windows USB:
   • Use a working computer to create a bootable Windows 11 USB using the Windows Media Creation Tool.
2. Boot from USB:
   • Insert the USB into your laptop, and boot into it (you may need to press F9 during startup to select the boot device).
3. Access Advanced Options:
   • Select Repair your computer → Troubleshoot → Advanced options → Command Prompt.
4. Rebuild Boot Configuration Data (BCD):
   • Type the following commands one at a time: bootrec /fixmbr
     bootrec /fixboot
     bootrec /scanos
     bootrec /rebuildbcd
      
   • Restart the computer.

Step 4: Reset BIOS to Default

If the issue persists, reset the BIOS to default settings:

1. Enter the BIOS/UEFI settings.
2. Look for an option to Restore Defaults or Load Default Settings.
3. Save and exit.

Step 5: Reinstall Windows

If none of the above steps work, you might need to reinstall Windows:

1. Boot from the Windows USB.
2. Select Install Now, choose the drive, and perform a clean installation.

I hope this helps. 

Take care and have a good day.
