Hi,
The 24 character error code is a failure of the short Disk Self Test ( DST ) and would indicate that the Hard Drive is failing and needs to be replaced.

Hi,
It means the hard drive has failed the quick test and needs to be replaced. If you can still boot into Windows backup all your personal files.
So what you need is a new 2.5" SATA3 hard drive from your preferred brand and capacity (2 TB limit because of thickness of drive)
Example:
or you could opt for an SSD such as the Samsung 860evo which would increase everyday performance of the PC.
On page 53 of service manual you can see the steps to replace the drive:

You will need to reinstall the OS on the drive, either by using recovery disks, migrating a backup image or by downloading media creation tool from Microsoft on different PC, running and creating a bootable pendrive with the OS on it. (there is explanation on the Microsoft web page on how to create the pendrive) Windows will automatically activate once installed and connected to Internet.

If you choose this option you will need to use the pendrive to perform a clean install of Windows 10. You might need to disable fastboot and secure boot in BIOS. So, insert the pendrive in the PC and it should boot directly from the drive. If not, turn off PC by holding power button. Press power button and immediately keep pressing ESC until startup menu appears and then press F9 and choose the pendrive in boot menu. Once it boots from pendrive follow the procedure to install Windows. You do not need a product key as it is in the firmware. Windows will automatically activate once installed and connected to internet.
When finished installing allow Windows to completely update and find all or most drivers. You can follow this process by going into settings > Security and update > click on Verify for updates. You might need to reboot a couple of times. Once completely updated you can go into device manager and see if there are any missing drivers (there will be yellow exclamation mark next to the device). You can find these drivers and software on HP support page for your product.
Once you have installed the OS you can try recovering files from the old drive with a SATA to USB adapter and connect the drive to the PC like an external drive:
