Hi @Macado69,

Error 3F0 means "Boot Device Not Found": the laptop can't find a drive to start from. After a recovery, this is often a boot setting.

  1. Unplug everything and hold the power button for 15 seconds.
  2. Press F10 for BIOS > Boot Options: make sure UEFI boot is used (Legacy off) and Secure Boot is enabled. Save with F10.
  3. Press Esc > F9 and choose "Windows Boot Manager" if it's listed.
  4. Run F2 diagnostics > Storage tests, as HP recommends for this error: https://support.hp.com/lv-en/document/c06225712
  5. If the drive passes but there's no boot entry, reinstall Windows from a USB made with the HP Cloud Recovery Tool.
