More info: I also replaced the cmos battery with a new one: no effect. My wife also has the same laptop and the same problem occured, It will not boot into windows but we can access the test environnement and all is ok, so I guess the hardware parts are ok but the pc can not access the repair pages, it stops booting and turn off.

This is the solution that was a success: Right on starting the start button I was holding the F10 to reach the Bios page. So far nothing special but here is what is new for me, I scrolled to the pages where is the Boot options, opened the Boot options and I selected (Secure Boot) did enter to change it from enabled to disabled. Then on the next line did enter on (clear all secure Boot Key) and redo it again to get the message Database is empty, then selected yes to load (HP Default Factor Keys), then select F10 to save and close that page. After that I had to reboot twice before all was getting back to booting normally in Windows 10.
