Hi @Aanchal2,

Welcome to HP Support Community.

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

The "Boot device not found" error, along with the message to install an operating system on your hard disk, typically indicates that your computer is unable to detect the hard drive or that the operating system on the drive is missing or corrupted. Here are some steps you can follow to troubleshoot and potentially resolve this issue:

1. Check Physical Connections

• Turn Off Your Laptop: Shut down your laptop completely and unplug it from any power source.
• Remove Battery: If your laptop has a removable battery, take it out.
• Open the Laptop: Open the laptop case or access panel (consult your laptop's manual for instructions if necessary).
• Check Hard Drive Connections: Ensure that the hard drive is properly connected to the motherboard. Check cables and connectors to ensure they are secure.

2. Run Hard Drive Diagnostics

Run Built-In Diagnostics:

• Restart your laptop and immediately press the diagnostic key (often F2, F10, ESC, or F12 depending on the manufacturer) to enter diagnostics mode.
• Select the hard drive test to check for any issues with the drive.

Check BIOS/UEFI Settings:

• Restart your laptop and enter the BIOS/UEFI settings (usually by pressing F2, F10, DEL, or ESC during startup).
• Navigate to the Boot section and see if the hard drive is listed. If not, it might indicate a hardware issue.

3. Check Boot Order in BIOS/UEFI

• Access BIOS/UEFI:
  • Restart the laptop and enter the BIOS/UEFI settings.
• Set Correct Boot Order:
  • Ensure that the hard drive is listed as the primary boot device. If it's not listed, you may need to check the connections or replace the hard drive.

I hope this helps.

Take care and have a good day.
