Oh, I understood alright. What you did not understand is what several of us told you, i.e. to learn a little bit of GRUB/GRUB2 and the booting sequence of the Linux kernel. But you found that it was either too intricate or too much work. I boot two different distributions with entirely different kernels, Windows 10, and some other junk, by having "duct-taped together" the grub.conf. So I am pretty sure that I understood what you wanted to do and I know it is possible with minimal effort. I know I am being of no help again, but perhaps it is time for you to start reading HOWTOs and other online documents again. Like Euclid told Ptolemy: "There is no `royal road' to geometry." You are better off learning the things you do not now. I hope this helps. I hope this message does not carry a condescending tone.
