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.

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.
