So after reading what "YannBuntu" has linked about the meaning of the *.efi.bkp and *.efi.grb. Does that effect your suggestion to add, "custom.cfg" with Code:

menuentry "Windows Boot Test" { search --fs-uuid --no-floppy --set=root CA62-F337 chainloader (${root})/EFI/Microsoft/Boot/bootmgr.efi } menuentry "2nd Windows Boot Test" { search --fs-uuid --no-floppy --set=root CA62-F337 chainloader (${root})/EFI/Microsoft/Boot/bootx64.efi }
Hope to hear from you soon, and Thanks for your quick reply
