you could first have a manual that explains grub in splendid detail, but once you get to the kernel being loaded and invoked, the grub manual is done -- its job is effectively over. then there is all the work done by the kernel as it starts to run and initializes your system (best understood, sadly, by reading the actual source in init/main.c in the kernel source tree). and once the kernel hands off control to "init", that's a whole new topic yet again. it's unlikely that a single document is going to cover all that -- your best bet is to just collect the best tutorials you can find on each phase, and tweak them so they mesh nicely.
They can't mesh other than by convention. When updating the config, kernel, initrd, etc., files you are working with the OS (doesn't have to be linux) view of the filesystem and it's relative locations. When grub boots, it only has the bios view of things and only sees one partition through the bios conventions.
