read the whole document here.
once understood, and check if it corresponds to your computer, try the proposed solutions
this often works:


rocedure 2: Ensure Legacy Support, under Boot Options, is DISABLED.
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


    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.
