That happens after install ubuntu on 2nd hdd and try boot from manjaro.
Selecting fallback initramfs boot is successful.

Also at startup loads grub with ubuntu display

Thank in advance.
and not manjaro format

you have installed version Ubuntu grub , that cannot
boot with microcode and img linux

can you see for a restore grub from manjaro
boot on USB iso manjaro

use for chroot

sudo manjaro-chroot -a
< command for grub-install >
exit ( quit chroot )

You have to repair GRUB. Manjaro’s GRUB must be the one installed last, and it needs to be in control.

Boot up from the Manjaro live medium, open up a terminal and and issue the following command… :arrow_down:

su -

Then issue the following command… :arrow_down:

manjaro-chroot -a

Select your Manjaro root filesystem from the menu and issue the following commands…

pacman-mirrors -f 5 && pacman -Syyu
grub-install --recheck --no-rs-codes --modules="part_gpt part_msdos"
sync && exit

Let the commands take all the time they need, even if it takes a long time. Then, when they’re finished, you should be safe to reboot.

[joe-Manjaro ~]# manjaro-chroot -a
==> Mounting (Ubuntu) [/dev/sdb1]
 --> mount: [/mnt]
 --> mount: [/mnt/home]
mount: /mnt/etc/resolv.conf: mount point is a symbolic link to nowhere.

Need to select some option to that command?

root@joe-Manjaro:/# pacman-mirrors -f 5 && pacman -Syyu
pacman-mirrors: command not found

Why ?

That’s why: you’ve chrooted into your Ubuntu installation.

Try it without the -a.

root@joe-Manjaro:/# manjaro-chroot
manjaro-chroot: command not found

You have to exit the Ubuntu chroot first, of course. Type…

pacman-mirrors -f 5 && pacman -Syyu
grub-install --recheck --no-rs-codes --modules="part_gpt part_msdos"
sync && exit

==> ERROR: Can't create chroot on non-directory

mkdir /manjaro
manjaro-chroot /manjaro
pacman-mirrors -f 5 && pacman -Syyu
grub-install --recheck --no-rs-codes --modules="part_gpt part_msdos"
sync && exit

[joe-Manjaro ~]# manjaro-chroot /manjaro
mount: /manjaro/proc: mount point does not exist.
==> ERROR: failed to setup API filesystems in chroot /manjaro

mount /dev/wherever/your/manjaro/is /manjaro
manjaro-chroot /manjaro
pacman-mirrors -f 5 && pacman -Syyu
grub-install --recheck --no-rs-codes --modules="part_gpt part_msdos"
sync && exit

Thank you very much for your help but i had to go .
I try tomorrow following your instructions.

A question just out of curiosity:
The Ubuntu grub is showing kernel version 2.6.32? This kernel is from 2010 or so. Which installation image did you use?


First of all I would like to mention that my long contact with ubuntu left me with remnants and a way to solve problems.
Let me explain.
I used applications eg (grub customizer) and I did not have much contact with the terminal and the essence of linux which I believe is the deep knowledge of the structure and interdependence of the components that make up the operating system in general.
On the other hand, I am old enough to deal with it now, but I will also try the fact that I do not know English well.
I would like you to tell me some link to learn what you think I should learn.
Now on to the topic I uploaded I solved it using the grub customizer but I would like to try to analyze the steps needed to solve a problem of this size sometime in the future.

Ubuntu, with Linux 5.4.0-47-generic
Ubuntu, with Linux 5.4.0-42-generic

mean 2020 maybe ?

This is weird because your 2nd image - screenshot of the ubuntu boot loader - says kernel 2.6.32. And this is really old.

That photo is downloaded (is NOT mine grub)and post it to notice references between the 2 login screen.

Don’t use grub-customizer in Manjaro. It’s not compatible with the already customized GRUB that Manjaro uses. It is however still offered in the repositories because Manjaro also offers grub-vanilla as an alternative boot loader, and grub-customizer does work with that one.

/dev/sda1 then. /dev/sda is your drive itself, and you cannot mount a drive. Well, you can, but only if there is no partition table and the drive has a single, large filesystem on it, and drives like that are not bootable.

It properly chroots into the on-disk installation, including the mounting of /dev, /proc and /sys within the chroot environment.

It fast-tracks five mirrors, synchronizes the databases and commences a full system update.

It installs GRUB to the default location for your platform (i.e. the master boot record of the drive in an MSDOS partition table, or the EFI system partition in a UEFI system), without the Reed-Solomon error-correcting codes (which are often problematic in UEFI setups), and with the modules to support both GPT and MSDOS partition tables preloaded.

I just install Ubuntu MATE alongside Manjaro MATE yesterday. To let Manjaro handle grub you have to reinstall grub from your Manjaro installation after booting with fallback initramfs:

First check where grub is installed:

[kunruh@thinkfreax ~]$ lsblk
NAME                                       MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
nvme0n1                                    259:0    0 476,9G  0 disk  
├─nvme0n1p1                                259:1    0     1G  0 part  /boot/efi
├─nvme0n1p2                                259:2    0    32G  0 part  
├─nvme0n1p3                                259:3    0    64G  0 part  /
└─nvme0n1p4                                259:4    0 379,9G  0 part  
                                           254:0    0 379,9G  0 crypt /home

In may case it is nvme0n1p1 (mountpoint is /boot/efi)

Then install grub:

sudo grub-install /dev/nvme0n1p1

and update grub:

sudo update-grub
