Booting failure, DST failure on HP 15, with 8.1 windows

[DC2016]

Hi when switching my notebook it displays

automatic repair and then displays for diagnosing PC for hours.

I tried to use F2 and found DST failure, and in the firmware management, the BiOS Update and Roll back failed stating the Signature File was not available.

How do I recover my data and restore my system? Looking for options and help

Hello,

Thank you for posting in the HP Support forum. Welcome!

I am afraid this is hardware problem - faulty Hard Disk drive (HDD). For details, you may provide me with the full error code that was present there.

However, since this is faulty HDD, you will probably not be able to recovery your files (more to follow).

Your options:

1) If your computer is still under warranty, please contact HP Support and inform them. They will work with you about the way to replace the faulty component.  Contact HP:

2) If your computer is with warranty period expired, you will need to replace the faulty HDD - buy it on your own. There are variety of options - vendors you can choose from - you need 2.5 inches HDD SATA. You can get it online or from PC retail store.

You can also consider installing SSD instead of HDD - this is strongly recommended as SSDs are way faster, more repliable and lighter. More info on SSDs:

How to replace the faulty HDD with new HDD or new SSD: please, find info and instruction in your computer's manual or watch YouTube videos examples for HP 15. If you do not want to do this on your own, please bring the computer (or ship it) to HP Authorized Service Center where the technicians will do this for you. If you are not sure where such a center is located, check these or contact HP for assistance in finding the nearest one for you:

3) Last part - once you replace the faulty component - you will need to reinstall back your operating system - Windows or another. So,

3.1 ) IF your computer originally came with Windows preinstalled by HP (a.k.a. OEM Windows), then you need to use HP recovery media - DVDs or USB pen drive you have previously created   or   recovery media purchased from HP. Some general info >> http://support.hp.com/us-en/document/c00006110

3.2) IF your computer did not originally come with Windows preinstalled but you later installed operating system on your own, you need to use the OS / Windows installation media and install Windows on your own.

Please, let me know how it goes and do post back if you need assistance. Looking forward to your feeback/reply.
