Hi!
Have you tried installing the operating system using the recovery discs?
Perform the following procedures to resolve this issue:
Procedure 1: Run diagnostics to rule out other hard drive issues.
Start or restart the computer.
Press F2 repeatedly during start up to enter the HP PC Hardware Diagnostics UEFI utility.
Select Component Tests > Hard Drive > Quick Test.
Select drive C:.
Click Run Once.
Once the test completes, results are displayed on screen.
If the drive passes all tests, continue to Procedure 2.
If the drive fails any of the tests, write down the failure ID (24-digit code) and contact HP Customer Support for further assistance.
Procedure 2: Ensure Legacy Support, under Boot Options, is DISABLED.
NOTE: If legacy boot support is enabled, you will NOT be able to see the Intel Optane entry as described in Procedure 3.
Start or restart the computer.
Press F10 repeatedly during start up to enter the BIOS configuration utility.
Check Legacy Support and disable if it is enabled:
System Configuration > Boot Options > Legacy Support
or
Boot Options > legacy Support
If Legacy Support is ENABLED, change it to DISABLED, save the changes and exit,
Lastly, try running a hard drive test from the system diagnostics page and check if the hardware is functioning correctly.
