HP PCs - 3F0 boot device not found error displays on a black screen in Windows 10

If the Hard Disk Error message displays when you start your computer, run the Hard Disk Test in System Diagnostics.

Identifying the hard disk 3F0 error

If the error message indicates 3F0 error or Boot Device Not Found, determine if your computer has Optane memory installed and configured correctly. See HP Consumer Desktop PCs - Boot Device Not Found (3F0) or Automatic Repair Errors for desktops or 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.

  4. If the hard drive passes the Quick Test, but there is still a problem with the hard drive, run the Extensive Test. This test includes the SMART Check, Short DST, Optimized DST, and Long DST. To run these tests individually, select them from the Hard Drive Tests menu.

  5. If the hard drive fails a test, click Troubleshoot.

  6. Follow the on-screen instructions to attempt to resolve the problem, and then click Yes.
