Bonjour,
Le but final était d'installer la partion UEFI sur mon SSD NVME M2 PCie. C'est sur ce SSD que j'ai fraichement installé Mageia 9 et je souhaite donc maintenant que l'UEFI soit situé sur ce SSD et non sur le disque Sata.
Cordialement;
    F.A.

Bonjour,
A partir du Live Mageia 9 sur USB j'ai téléchargé Grub2 et Grub-customizer.
Malheuresement ce dernier génère le m^me type d'erreur :

grub2-mkconfig ne peut pas s'exécuter correctment. Message d'erreur :
/usr/sbin/grub2-probe: erreur: impossible d'obtenir le chemin canonique de "overlay".

Cordialement,
    F.A.

Pour info, (si cela pour vous e^tre utile), j'ai essayé la commande suivante :

[live@localhost ~]$ grub2-probe -v /dev/nvme0n1p1
grub2-probe : information : impossible d'ouvrir « /boot/grub2/device.map » : Aucun fichier ou dossier de ce type.

The UEFI partition is called the ESP (EFI System Partition). Changing it on a configured system could be hazardous...

OK, your ESP is currently
 /boot/EFI size: 511 MiB used: 7.9 MiB (1.5%) fs: vfat dev: /dev/sda1
and you want to move it to
 /dev/nvme0n1p1 size: 512 MiB fs: vfat

You have already created the new ESP; does it have type 'EF00'?

We have not mentioned NVRAM, but that has pointers to the ESP, and will need changing from the old to the new. I am unsure whether install-grub removes things from NVRAM. This gets delicate if you do not want to have an unbootable machine.
Post the output of
 # efibootmgr
If you do not have 'tree', install it; it is useful. Then post
 $ tree /boot/EFI
or if you have other systems (to limit output)
 $ tree -d /boot/EFI

You mention various Grub failures, but not exactly what you were doing. Were they all from a Live system? What exactly were you asking Drakboot to do - all the exact steps?

I don't know how to get the type of ESP ...

Probably:

gdisk /dev/nvme0n1

then i

then 1

If its not 'EFI System Partition' you can use gdisk to change it using l to get a list of the type codes and the t command to change it.

CC: (none) => zen25000

I do not change because ESP is already an EFI system partition with type "ef00" ==> See below, the result of gdisk t command.

Thanks Barry for intervening.
I did not like the gdisk error when citing just the partition, but found the same thing (and worse!) on my own system! Citing just the device produced normal output...
The new ESP looks correct.

Please post the output of:

Thank you for all the information.
It would be nice to have also the output of the original ESP contents with
 $ ls -R /boot/EFI

The Grub update will need to (1) put the Mageia booloader in
 EFI/mageia:
  grubx64.efi
on the new ESP. (2) Change the mageia NVRAM entry to point to disc 2.
What are you going to do for Ubuntu?

Now I repeat the end of comment 8:
Please describe precisely what you did to see the original error.
You say in comment 0 that you were working from a Plasma Live USB. Was this doing the installation of the system on /dev/nvme0n1p2 ? Can you say exactly what you did/chose/specified at the Bootloader installation stage?

Once again, CC'ing Martin to cast an eye on this.

Ubuntu was only a test carried out on a disk dedicated to various tests.
So it's not important to keep it in the new ESP.

658 / 5 000
When I installed "Mageia 9", I left all the disks plugged in.
The installation of / on /dev/nvme0n1p2 went well but it was on the boot of /dev/sda that GRUB was modified. So I always boot via disk /dev/sda (disk that I want to free).
When the problem happened, I unplugged all the disks except /dev/sde which contains the /home (and the .M2 SSD of course) and I started the live Mageia 9 USB to try to Repair/Install GRUP on the new ESP (/dev/nvme0n1p1) when trying to update the previously installed Mageia 9.
This did not allow changing the destination and the problem appeared.

The Live ISOs don't provide an option to upgrade an existing installation, or to repair/install GRUB. Did you actually use the classical installer ISO? To clarify, tell us the exact name of the ISO file you copied onto the USB stick.

To do what you want to do, I would do the following:

1. Boot the installed system with the old disk (/dev/sda) still connected.

2. Using drakdisk
  - Select the old ESP partition (/dev/sda1)
  - Unmount the partition
  - Change the mount point from "/boot/EFI" to blank
  - Select the new ESP partition (/dev/nvme0n1p1)
  - Change the mount point to "/boot/EFI"
  - Mount the partition
  - Exit, saying yes to saving the modifications in /etc/fstab

3. Check that /boot/EFI is now accessible.

4. Run drakboot. It should report that no bootloader is detected. Proceed to installing the bootloader of your choice.

And finally

5. In a terminal window, as root, run "dracut -f"

This updates the copy of /etc/fstab in the initrd image. If you don't do this, systemd will try to mount the old ESP during the early boot stage, which will probably cause the boot to hang if you disconnect the old disk.

I have two USB sticks; one with Live Mageia 9 and another with the classic 64 bit installation. The installation of Mageia 9 on /dev/nvme0n1 was carried out with the key containing the classic installation (Mageia-9-x86_64.iso).
As the Live USB could not modify the installation I used the installation USB key to try to repair/modify/move the ESP partition.

Martin has provided super instructions. Over to you.

Good morning,
with a little delay, I have just carried out the operations that Martin suggested. Everything worked fine and now the ESP is on the SSD.
Many thanks to Lewis, Barry and Martin for helping me resolve my ESP migration issue.
I think that the "drakboot" crash was caused by the fact that I had unplugged the sda ​​disk that the boot was installed on.
Long live Linux and long life to Mageia which benefits, thanks to you, from very efficient technical support.
Sincerely,
 F.A.

Thank you for the update, Frédéric.
And thanks for helping out, Martin.

I think we can close this bug as invalid or worksforme.

But before that, a question:
Is there something we should improve in some documentation or tool?

CC: (none) => fri

Yes, you can close this ticket.

Here is what could be improved:

1) For drakboot:
Perhaps a more explicit error message would be welcome, when the disk, containing the ESP, is inaccessible (or unplugged in my case ;-(().

2) For ESP:
The case of moving the ESP, from one disk to another, (notably to an SSD), could give rise to a tutorial in a Wiki for example. An automation tool would also be welcome.

Sincerely.
 F.A.

Hmmm If you disconnect a disc being used... The error message came from grub, not drakboot.

Possibly, when someone has the time. Comment 23 comment 24.
It is such a rare requirement, and it may even be possible to have more than one ESP anyway. The problem more specifically was how to get the bootloader installed in the new ESP and referenced there from NVRAM.
