Apologies! I didn’t keep my word and stick with what @dalto suggested!
I couldn’t take it to find a simpler boot loader and easier to fix, and less prone to breaking and not go for it! It is a matter of principle for me!
But still I followed @dalto at his wonderful tutorial [Tutorial] Convert to systemd-boot
I have documented the steps I made step by step, hoping it might help those like me who just need steps 1, 2, 3, DONE! [Tutorial] Convert to systemd-boot - #138 by limotux
I hope it helps and adds to the forum.
