Translations:Preserve Manjaro Bootloader/13/en

Whenever we install another OS, it will be at the top of that bootorder; and we will need to reorder such that Manjaro is again at the top. And we can do that at that install livecd media itself. If we forget, we can do it after installation at any OS. For UEFI, we can still select Manjaro to boot at boot-setup (one of F8 ~ F12).
