Hard disk not found on hp envy 15 I did Hard drive check, it show SMART CHECK: NOT INSTALLED, SHORT DST : NOT INSTALLED I try change the hard disk still not working even bought new harddrive flex cable still nothing…please I need help.

If the Hard Disk Error 3F0 boot device not found is displayed on a black screen, run the Hard Disk Test in System Diagnostics. Note: If the error message indicates a 3F0 error or Boot Device Not Found, determine if your computer has Optane memory installed and configured correctly. Regards, Will
