Clover reinstalled yesterday ( Paris CET) Installing BootSectors/BootLoader as shown below, but no change. "no operating system" after the boot. And the OS/X HDD EFI partition is not usable via the boot menu of the Bios (Bios is UEFI compatible : i can boot on the stick )
I must boot via the USB stick to have OS/X working. Before the 10.11.3 update all was working.
The EFI partition is writable.
