[SOLVED] error: file /vmlinuz-linux not found in btrfs

Hello! I was recently updating my system, when it just froze mid update completely, and I was forced to reboot. What I didn't realise was that the update included some stuff for

linux

and firmware updates for it.

I have gone through some previous threads which referred to the same issue, but with not much success.

I apologize that I am only able to provide pictures, as I am aware it isn't convenient for people with sight disabilities.

Here is the error that grub shows:

https://files.catbox.moe/5u18fs.jpg

I tried chrooting into my arch install via a live USB, I tried running

sudo pacman -S linux

and also

sudo pacman -Syu

.

This does generate a

vmlinuz-linux

file in

boot

.

Here are some pictures for the same:

https://files.catbox.moe/e5ul0v.jpg

https://files.catbox.moe/ci3qmz.jpg

However, this doesn't solve the issue and blurts out the same error as shown in picture 1. i.e. GRUB being unable to find

/vmlinuz

What can I be doing next?

How sure are you you don't have the ESP mounted to /boot normally and didn't do so on these reinstall attempts? Mount all partitions as you expect them to be under the path you will chroot in (e.g. / on /mnt, /boot on /mnt/boot and so forth) chroot in and rerun the installation command.

My apologies.

Prior to this, I also tried mounting the boot partition to /mnt/boot/ , which didn't yield any tangible results either.

I will mention this, I use Legacy BIOS so the ESP part might have been unnecessary.

I also followed the guide on the arch wiki for chrooting and adjusted them for my set up

Here is my lsblk

 
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
loop0         7:0    0   1.8G  1 loop 
loop1         7:1    0   7.6G  1 loop 
├─live-rw   253:1    0   7.6G  0 dm   
└─live-base 253:2    0   7.6G  1 dm   
loop2         7:2    0    32G  0 loop 
└─live-rw   253:1    0   7.6G  0 dm   
sda           8:0    0 465.8G  0 disk 
├─sda1        8:1    0   200M  0 part 
└─sda2        8:2    0 465.6G  0 part 
sdb           8:16   1   7.3G  0 disk 
├─sdb1        8:17   1   7.2G  0 part 
└─sdb2        8:18   1    32M  0 part 
sdc           8:32   1     0B  0 disk 
sr0          11:0    1  1024M  0 rom  
zram0       252:0    0   3.7G  0 disk [SWAP]

Here, sda is my laptops HDD, sdb is my live install and sdc is my phone via which I USB tether to get internet

And here are the commands I used for mounting my stuff

 
# mount /dev/sda1 /mnt/boot
# mount /dev/sda2 /mnt
# mount -t proc /proc proc/
# mount -t sysfs /sys sys/
# mount --rbind /dev dev/
# chroot /mnt/@ /bin/bash

Am I doing this right? It might be wrong considering the fact that I probably shouldn't be mounting sda1 as boot. Rather, I should be mounting /dev/sda2/boot at /mnt/boot.

Re: [SOLVED] error: file /vmlinuz-linux not found in btrfs

# mount /dev/sda1 /mnt/boot
# mount /dev/sda2 /mnt

The order is off.
You're mounting /dev/sda1 to /mnt/boot and then shadow that partition by mounting /dev/sda2 to /mnt

# mount /dev/sda2 /mnt
# mount /dev/sda1 /mnt/boot

How does that matter? Just out of curiosity

Edit: figured it out nvm

Re: [SOLVED] error: file /vmlinuz-linux not found in btrfs

Update: Pacman is complaining that it is unable to detect the root filesystem.

pacman log

Here is how I went about mounting this time:

# mount /dev/sda2 /mnt/
# mount /dev/sda1 /mnt/boot
# mount -t proc /proc proc/
# mount -t sysfs /sys sys/
# mount --rbind /dev dev/
# chroot /mnt/@ /bin/zsh

[2023-02-22T04:50:16+0530] [ALPM-SCRIPTLET] ==> ERROR: /proc must be mounted!

Sorry, didn't pay enough attention

# mount -t proc /proc proc/
# mount -t sysfs /sys sys/
# mount --rbind /dev dev/
# chroot /mnt/@ /bin/bash

is off as well
You need to enter /mnt before mounting /proc
https://wiki.archlinux.org/title/Chroot
If you're doing this from the install iso, you can also just use arch-chroot after mounting /mnt and /mnt/boot

Maybe it is a bit late, but I want to mention that I use BTRFS (you will see why I am mentioning this)

I downloaded the iso for arch and did the following:

# mount /dev/sda2 /mnt
# mount /dev/sda1 /mnt/boot
# arch-chroot /mnt

This results in arch-chroot complaining that:

mount: /mnt/proc: mount point does not exist
             dmesg(1) may have more information after failed mount system call.
==> ERROR: failed to setup chroot /mnt

But, now I did the following:

# ls /mnt
boot   @.  @.snapshots   @home   @log   @pkg

This slipped my mind completely and was also present in one of the screenshots, that my proc is at /mnt/@/proc, NOT /mnt/proc.

Perhaps arch-chroot assumes you are using EXT4 or smth?

I tried mounting proc at /mnt/@proc and same for boot and also the same for rbind dev and sysfs

Still no avail

Re: [SOLVED] error: file /vmlinuz-linux not found in btrfs

You have to specify the subvol option when you mount it, same way you did when you installed the system.. See the btrfs wiki page.

I just did arch-install and let it do its thing

What should i be looking for in the wiki?

archinstall is not a way of avoiding knowing how your system is set up. You take shortcuts in Arch, the WILL come back to bite you.

Re: [SOLVED] error: file /vmlinuz-linux not found in btrfs

After roughly 12+ hrs of head banging, I have finally gotten it fixed!

BTRFS mounts differently than ext4(shocker), the Arch Wiki doesn't mention that in the chroot wiki, but thx to Scimmia I was able to figure it out.

Arch by default creates the following subvolumes for BTRFS:

@.   @home   @.snapshots   @log   @pkg   boot 

The one of interest here is "@." aka the root folder

Mounted it by:

# mount -t btrfs -o subvol=@. /dev/sda2 /mnt

Reference Wiki

I personally didn't need to go any further, as the root directory itself contains the boot folder. The other boot folder (/dev/sda1) was the one with GRUB, no need to touch that

From there, I chrooted by:

# chroot /mnt /bin/bash

After chrooting, I could run the usual commands:

# pacman -S linux

After regenerating the initcpios, I could breathe the sigh of relief knowing that proc mounting issue I had earlier was fixed

Sure it did throw an error up later but the thing I wanted actually was fixed

Big thanks to V1del and seth for helping the Arch Forums community for a very long time, you guys have helped me fix issues and guide me for a while now <3

Thank you so much Scimmia for leading me in the right direction.
