How to resolve this problem?

Hello @Farei,

The failure 3F0 means your Hard Drive has Failed & needs to be replaced. 

If your notebook is still under warranty, contact HP and arrange to have the drive replaced.

Please do a HDD self test first:

1. Restart the computer.
2. Keep tapping the F10 key when the HP logo appears. This will take you to Bios Setup Utility.
3. Select the Diagnostic tab.
4. Select the "hard drive self test" option and press enter to perform the test.
Note: This test takes arond 40 minutes or more.

Pass - The hard drive is not damaged.
Fail - the hard drive is damaged and may need to be replaced.

Hi,

Usually this means your hard drive has failed and needs to be replaced. You can try running HP diagnostics on the disk  at startup.

You will need to replace with 2.5" sata drive. You can opt for an SSD which will greatly enhance everyday system performance.

You will need to reinstall windows either by downloading the media creation tool from, Microsoft and creating a bootable drive with windows 8.1 on a different computer. Or using HP recovery disks.

Hope it helps,

David
