For me this is a fatal mistake! But anyway thanks to this incident I looked around and found rEFInd which is OK, but I found systemd-boot
much simpler. So, I just did it and converted to systemd-boot
thanks to @dalto and his tutorial [Tutorial] Convert to systemd-boot
By the way, I am not by any means saying Grub is bad or rEFInd is not that good.
As long as there is software there are bugs.
I just thought this is what suits me more! Simpler and easier to maintain or fix (I think) if it happened!
So far so good and enjoying.
