I'm not sure if the solution to your problem is to install everything 
manually. I have no problems getting `make modules_install install` to work 
properly and find GRUB2 because openSUSE provides the "dracut" package for the 
sysadmins/developers to automate the above. 

It's perfectly fine to teach how to install manually, even if just for people 
to learn what one needs to boot a custom kernel. But kernel developers don't 
have time to manually do routine tasks that can be easily automated. 

I use to compile and install the kernel image, the modules, init, System.map, 
config, and grub.conf at least two or three times a day and often more times 
(you'll understand when you find yourself doing a bisect with git-bisect and 
maybe you have to compile and install a dozen times in a row in one day). 

In my opinion you need to make sure you understand and explain how to install 
"dracut" if your distro provides it. Otherwise, search and read the 
documentation of your distribution and try to figure out how to make the `make 
modules_install install` command to work properly in your system...
