Yes, 

in the most time it works not ;) I have test it a whole afternoon (20-30 
restarts ) it works, In the evening I test it again but it works not and is 
not longer working.

Next day I test It again it works 5 or 10 times afterward it works not.

The config from the os-prober.

### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows Boot Manager (on /dev/sda1)' --class windows --class os 
$menuentry_id_option 'osprober-efi-CEA4-BE10' {
        insmod part_gpt
        insmod fat
        set root='hd0,gpt1'
        if [ x$feature_platform_search_hint = xy ]; then
          search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt1 --hint-
efi=hd0,gpt1 --hint-baremetal=ahci0,gpt1  CEA4-BE10
        else
          search --no-floppy --fs-uuid --set=root CEA4-BE10
        fi
        chainloader /efi/Microsoft/Boot/bootmgfw.efi
}
### END /etc/grub.d/30_os-prober ###
  
After Starting oS os-prober always found Windows ?

Linux EFI is installed on the second Disc (/dev/sdb1)
