Computer won't boot after Kernel update

[Sophoruz]

Hello, after installed the new kernel, everything I could got is a black screen so I switched back to 5.8 and it was fine until a new update that once again doesn’t pass from the motherboard screen, it seems like a problem with Nvidia drivers too. I am still new on Linux.

Hello, and Welcome to Manjaro. Next, I really do not know anything about Nvidia but here some tips:

1. Use the Search button and you will find a lot of information.

2. Please read this:

[HowTo] Provide System Information

This tutorial is superseded by this one. Remember all Tutorials are wiki posts that can be edited by TL2 (Trust Level 2) members and above. Welcome to Manjaro! To allow all of us helpful people on this forum TO HELP YOU, we need some basic information about your system. This probably means you described the symptoms of your problem, but now we need some more information to know where the origin of your issue is exactly. Someone else probably linked you to…

You will learn a lot about your problem. I would bet it is a question of which version 450 or 455.

good luck

This is what I get on kernel 5.8.

Sorry for the picture but I can’t copy/paste. Also not sure if I should take pictures of the results from commands listed on How to provide good information.
Sincerely I have no idea what to do.

[HowTo] Resolve an unbootable Manjaro (black screen, login failed, cant boot, etc)

When we have problems gaining access to our systems it is difficult to gather information, let alone fix any problems. Here we will cover common causes and solutions to ‘manjaro wont boot’. TTY If your desktop does not load properly then you might still be able to use most, if not all, functionality by dropping to a non-graphical TTY. By default your system will have multiple TTYs, with each corresponding to an Fx key. Your desktop is assigned to one as well - most often F1. You can chang…

[How To] Save your Manjaro installation when it breaks

Difficulty: ★☆☆☆☆ Post original authored by Heart-Of-A-Lion Some of you might have had it happen, a Linux installation on your computer that breaks after installing certain software, after installing updates or after editing a configuration file. Sometimes you mess up so bad, that the entire system doesn’t boot past Grub or doesn’t even boot Grub itself if you messed around with its configuration files. So what can you do when you really messed up big time? What if you didn’t make that Clon…

However when I insert this command

sudo pacman -S manjaro-chroot

I get this.

[manjaro@manjaro ~]$ sudo pacman -S manjaro-chroot
error: target not found: manjaro-chroot

However when I insert this command

sudo pacman -S manjaro-chroot

I get this.

[manjaro@manjaro ~]$ sudo pacman -S manjaro-chroot
error: target not found: manjaro-chroot

That is the command. The package is called manjaro-tools-base.

$ sudo pacman -F manjaro-chroot

boot on USB iso manjaro
open a terminal and a browser on this topic
and returns

sudo manjaro-chroot -a
mhwd-kernel -li
mhwd -li
inxi -Fza
exit ( quit chroot )

[Sophoruz]

[manjaro@manjaro ~]$ sudo manjaro-chroot -a

If I type 0 instead of 1 I get the same:

[manjaro@manjaro ~]$ sudo manjaro-chroot -a

[stephane]

with btrfs , yo ucant use command manjro-chroot
you have to use this one

you can use manjaro-chroot this way
( recheck disks partitions before )

sudo mount -o subvol=@ /dev/sdaX /mnt
manjaro-chroot /mnt

done
or

sudo mount /dev/sdaX /mnt
manjaro-chroot /mnt/@

if you want to install grub
for uefi
you can
mount efi partition before hand
consider
/dev/sdaX is root partition
/dev/sdaY is efi partition

sudo mount /dev/sdaX /mnt
sudo mount /dev/sdaY /mnt/@/boot/efi
manjaro-chroot /mnt/@
