Many submenu-options at the grub list vanished

[fehlix]

...if you have an iso live you will see these options over there too ...

Did you added those manually from the live ISO?
Those are on the live ISO:

Debian and Linuxmint are not installed anymore(?)

Thanks for the output, nicely done.
I now realize, I screwed up, and need to beg for more info.

I should have asked for:

Code: Select all

LANG=C efibootmgr --verbose

so we can verify that "Boot0003* MX19" goes where we expect.

Are you asking for to run boot repair and Install on: ESP and Click Apply?

Not yet.

They're EVERYWHERE! 3rd time today!

That is what you said before ... what can i say? ... these options were here before in my installed system and now they are not here anymore you are the experts i'm nobody, but i'm telling you what happened, it vanished from my system, if you don't believe what i said, case closed.

Don't worry, I believe you. Can you remember what have changed before you missed those entries?
Any major updates or did removed something else?
Can we see what's on those folder
do run

Code: Select all

ls -dl /etc/grub*/* /boot/grub/*

One day i saw them, it was at the beginning of having installed the system; i had problems with Manjaro then i went into one of this entries to fix Manjaro ... i had grub-customiser installed, so i don't remember more about it. Those entrances were hidden, they were not visible, and I will never return to look until yesterday that i had another problem with Manjaro ...

Either way if they're not supposed to be there then it doesn't matter much.

Looks reasonable, I think, (not sure of the LinuxMint entry):
Active:

• #3 MX19 --> ESP partition, file: /EFI/MX19/grubx64.efi
• #1 manjaro --> ESP partition, file: /EFI/manjaro/grubx64.efi
• #4 endeavouros --> ESP partition, file: /EFI/endeavouros/grubx64.efi

Inactive:

• #5 debian --> ESP partition, file: /EFI/debian/shimx64.efi
• #1 LinuxMint --> ESP partition, ??? VBR(Volume Boot Record)/PBR(Partition Boot Record)?

So, you should be getting to the MX-19 Grub menu, and I think you are.

What's present on the MX-19 Grub menu(s) should be modifiable by adjusting the grub config on MX-19 and updating grub from MX-19.

Somebody else told me in another foro that because this is an UEFI wherever... something like a mark (my own words) will remain in the BIOS, then i checked at that moment and Debian and MInt were there even when i uninstalled both of them.

It is different at Gparted:

And at the Bios the order is like this:

*MX19
Debian
LinuxMint
*Manjaro
*Endeavouros

Very good question!
You don't see it. The EFI-(grub)-loader get loaded by the UEFI-firmware.
The "efibootmgr -v" does only show the efi-loader on the ESP (EFI System Partition) which has been registred into the firmware NVRAM.
The magic is within the EFI-(grub-)loader, e.g. within /boot/efi/EFI/MX19/grubx64.efi.
Within this efi-"binary" /boot/efi/EFI/MX19/grubx64.efi the location of the boot/grub-partition is burned into.
