Hi @Daniel324,

Welcome to the HP Support Community. 

I'd like to help!

To be able to answer you effectively, we need some information.

May I have the exact product name and number? Refer to this document for steps to find the product details. Do not share any of your personal information such as serial, phone number, email ID, etc.

Meanwhile, Perform the following procedures to resolve this issue:

Procedure 1: Run diagnostics to rule out other hard drive issues.

1. Start or restart the computer.
2. Press F2 repeatedly during start up to enter the HP PC Hardware Diagnostics UEFI utility.
3. Select Component Tests > Hard Drive > Quick Test.
4. Select drive C:.
5. Click Run Once.
6. 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.

1. Start or restart the computer.
2. Press F10 repeatedly during start up to enter the BIOS configuration utility.
3. Check Legacy Support and disable if it is enabled:
   
   System Configuration > Boot Options > Legacy Support
   
   or
   
   Boot Options > legacy Support
4. If Legacy Support is DISABLED, skip to Procedure 3, Step 3.
   
   If Legacy Support is ENABLED, change it to DISABLED, save the changes and exit, then go to Procedure 3.

Procedure 3. Determine if Optane memory is installed and working normally.

1. Start or restart the computer.
2. Press F10 repeatedly during startup to enter the BIOS setup utility.
3. Look for the Intel(R) Rapid Storage Technology option; navigate to:
   
   System Configuration > UEFI HII Configuration > Intel(R) Rapid Storage Technology
   
   
   
   If Intel Optane is not listed, the computer does not have Optane memory or Optane memory is malfunctioning and cannot be detected. Contact HP Customer Support for further assistance.
   
   If Intel Optane is listed, the computer has Intel Optane memory installed and working normally. Continue with procedure 4.
