Hi @Momin-01,

Welcome to HP Support Community.

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

The "boot device not found" error typically indicates that the laptop is unable to detect the hard drive or the operating system installed on it. Here are steps you can take to troubleshoot and potentially resolve this issue.

Check BIOS/UEFI Settings

Access BIOS/UEFI:

• Restart your laptop and press the appropriate key to enter BIOS/UEFI settings. Common keys are F2, F10, Esc, or Del. The exact key should be displayed on the screen during the boot process.

Check Boot Order:

• Ensure that your hard drive is listed as the first boot device. If it's not, change the boot order so that the hard drive is first.

Check Hard Drive Detection:

• Verify that the hard drive is detected in the BIOS/UEFI. Look for the storage or information tab to see if the hard drive is listed.

Run Hardware Diagnostics

1. Built-in Diagnostics:
   • HP laptops often have built-in diagnostics tools. You can access them by pressing F2 or F10 during boot (this might vary by model).
   • Run the hard drive test to check for any hardware issues.

Check Physical Connections

1. Inspect the Hard Drive:
   • Turn off the laptop, disconnect the power adapter, and remove the battery (if possible).
   • Open the laptop's back panel to access the hard drive.
   • Ensure that the hard drive is properly connected to the motherboard. Re-seat the connections if necessary.

Repair or Reinstall Windows

Using Windows Recovery Media:

• If you have a Windows 10 installation media (USB or DVD), insert it into the laptop.
• Boot from the installation media by pressing the appropriate key during startup (usually F9 or F12 to select the boot device).
• Choose the option to repair your computer.
• Select "Troubleshoot" > "Advanced options" > "Startup Repair" to attempt a repair.

Reinstall Windows:

• If the above steps fail, you might need to reinstall Windows. During the installation process, you can choose to keep your files or perform a clean install. Be aware that a clean install will erase all data on the drive.

Consider a Failing Hard Drive

If the hard drive is not detected at all or if diagnostics indicate a failure, the hard drive may be faulty. In this case:

Replace the Hard Drive:

• If you have a spare hard drive or SSD, you can try installing it in the laptop.
• Reinstall Windows on the new drive.

Data Recovery:

• If you need to recover data from the failing drive, you might consider using a USB hard drive enclosure or a docking station to connect the drive to another computer. Specialized data recovery software can then be used to attempt data retrieval.

I hope this helps.

Take care and have a good day.
