EFI Files and EFI Boot Partition

This is my recent discovery.

EFI is only 512 in my case.

It is a FAT partition.

I do not format (one should not-no booting) it to avoid erasing previously installed distributions.

I have had no problem with installing Debian Gnome and it detects the existing distributions and update it. It does not record previously erased distributions. 

It only records current existing ones.

This is not so with Elive. However, gets it correct after several attempts at installation but it writes a new GRUB file of its own.

Now with Endeavour OS it goes into blank and runs only Endeavor OS and thankfully no damage done to EFI partition and other previous Boot Files.

Yesterday, I installed Rocky Linux and erased it immediately.

I am sure it did not do any damage to the GRUB file. 

I solved all the problems by Installing Manjaro but I got it right on the 3rd attempt.

Today I installed under Gnome,

MATE

CINNAMON 

Compiz 

IceWM

Now I get a boot Menu that is common to BSD. 

It is graphical and not text menu.

It is called rFind, probably coming from BSD.

How Come?

I do not know?

I put the blame on Compiz (I do not think it can) but I cannot mount a Compiz as a desktop.

Any way, I have no qualms at all.

I erased it using Gnome.

Not the boot menu is graphical and it is good with my poor eyesight.
