HP Envy x360 Convertible 15-cn1000na
Microsoft Windows 10 (64-bit)

Evrey test has been done, all ok.

In forums it states the optane memory is corrupt. on BIOS it does not show an optane installed???

@dave19561 Welcome to HP Forums Community!

 

NOTE: 

If the error message indicates 3F0 error or Boot Device Not Found, determine if your PC has Optane memory installed and configured correctly. See HP Consumer Desktop PCs - Boot Device Not Found (3F0) or Automatic Repair Errors for desktops,HP Consumer Notebook PCs - Boot Device Not Found (3F0) or Automatic Repair Errors for notebooks. For more information about Optane memory, see HP PCs - Installing and Using Intel Optane.

 

If the BIOS isn't showing the optane memory because you don't have one installed physically, please go through the below steps to resolve the issue:
