HP, "no bootable image found", only on restart !

[jazz4ever]

Hi guys, HP0460P, "no bootable image found", only on restart ! I tried to replace that SSD (Samsung 870 evo 500gb), with other 2 ssd, everything goes ok; I put that ssd in other laptop (hp 8570p), all was ok; 

  I reinstalled win 10, same problem; I cloned hp8570p, to hp8470p, same problem ! If I change "UEFI native", to "legacy", apear another problem "no boot device found") !

 I mention, the problem started two weeks ago and only on restart, only on the hp8470p laptop and only with the samsung 870evo 500gb ssd !!! (x-files !)

Thank you !

The internal drive on any recent laptop is set to boot only in UEFI mode.  Changing it to Legacy mode will GUARANTEE that it will no longer boot.

Also, reinstalling Windows, unless you use an HP OEM supplied version, will also GUARANTEE that you will not get the drivers you need.  Windows only installs MS default generic drivers, not the custom drivers from HP.
