=================== Suggested repair
The default repair of the Boot-Repair utility would not act on the MBR.
The boot flag would be placed on sda1.
=================== User settings
The settings chosen by the user will not act on the boot.
Je pense comme geole (post #5) qu'il faut réinstaller Windows 10.
