[SOLVED]System can't find devices at boot and fails to start

ordinary.schreiber · 2023-08-09 16:37:26

Hello, I have Xfce on my Laptop (dual boot with Windows 11) and never encountered this type of issue.

What I did was performing a usual system update via pacman -Syu. Then at reboot the system failed to boot and I got a black screen saying:

ERROR: device 'UUID=108931b1-6e0a-41ef-b67d-220021fd779f' not found. Skipping fsck.
mount: /new_root: can't find UUID=108931b1-6e0a-41ef-b67d-220021fd779f.
ERROR: Failed to mount 'UUID=108931b1-6e0a-41ef-b67d-220021fd779f' or real root.
You are now being dropped into an emergency shell.
sh: can't access tty: job control turned off
[rootfs ~]#

The dual boot with Windows 11 is made from a partition of the same NVMe SSD, and it still works. Can somebody help?

Thank you in advance.

lsblk -f

Don't transcribe that, in doubt link a screenshot

ceterum censeo: 3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Thanks for you suggestion. I tried typing in the command but unfortunately the keyboard is not working, it seems frozen or something.

About disabling the dual boot, can I do that without entering commands? Or how can I solve that first?

You disable that from windows, actually read the linked wiki.

You might have to fix linux offline, boot the install iso, and post (1st link below) the output of "lsblk -f", then mount the installed system, the boot partition, and also post "pacman -sysroot /mnt -Qs kernel" and "file /mnt/boot/vmlinuz*" outputs.

I had exactly the same problem with booting after latest update. The only difference is that I have no dual-booting config.
I've solved this problem with booting from the Arch installation medium, mounting my existing partitions, chrooting into my system and recreating initramfs image with

mkinitcpio -P

Great, this solved it. Thank you both!

I have this problem few times a month, is there a way to prevent this? mkinitcpio -p fixes it every time.

Check your pacman log, mkinitcpio is (supposed to be) called whenever you update anything kernel related.
There seems to be an issue w/ that.

I did found now that I had /etc/mkinitcpio.conf.pacnew file, and did override my old one, se lets hope that this fixes my issues.

Pacman log did not show anything strange to me.

overwrote your old one? You're supposed to merge changes. Now the changes you'd previously made are gone, and your system may not boot at all.

Do you have a copy of your previous mkinitcpio.conf ?

balthamaisteri · 2023-10-07 11:00:13

So actually I did find out an error from pacman.log, updating mkinitcpio.conf did not fix the issue. I am quite sure that the issue is with my HENYX usb sound mixer. Every now and then update does something that makes henyx disconnect / reconnect and when that is happening mkinitcpio fails? Or something like that. No idea how to fix this one, but I will just probably do without my soundfixer.
