other devices.
4. Use the HP Hardware Diagnostics tool to verify the drive is recognized and test it.
5. If the hard drive fails diagnostics, record failure and have the drive replaced.
6. Identify when the issue is related to software. If the hard drive passes diagnostics, test
the drive on a verified working computer. If the failure follows the drive, reinstall the
operating system to make sure software is not an issue.

drive as this may resolve related issues.
Procedures
Possible causes
Operating system, loose connection, faulty hard drive, BIOS configuration, Secure Boot.
Troubleshooting steps
1. Verify if Secure Boot is enabled in BIOS. Secure Boot prevents legacy boot devices from
starting the computer, including bootable CDs and DVDs. For more information, see
http://support.hp.com/us-en/document/c03653226.
2. Reset BIOS to default. Be sure that BIOS Boot Mode in Boot Option is set up properly
for bootable device and its operating system (i.e., UEFI Native for Windows 8).
Another example, choosing Legacy Boot Order for an UEFI device will cause "Boot
Device not found (3F0)" error.
3. Verify hard drive connection and flex cable. Reseat connection. For multiple storage
devices, keep the primary drive with the operating system and remove other devices.
4. Use PC Hardware Diagnostics tool to test. Record failure code and have the hard drive
replaced.
5. If there is no error, reinstall the operating system using HP Restore.
6. Test with a verified working operating system hard drive, if available.
