I’d suggest booting into a live environment, from there enter a chroot
environment, where you’ll be able to execute the commands and run any to try and resolve this.
How to chroot
-
Ensure you’ve got a relatively new ISO or at least one with a still supported LTS kernel.
-
Write/copy/
dd
the ISO to a USB thumb drive. -
When done, boot with the above mentioned USB thumb drive into the live environment.
-
Once booted, open a terminal and enter the following command to enter the
chroot
encironment:
manjaro-chroot -a
- If you have more than one Linux installation, select the correct one to use from the list provided.
When done, you should now be in the chroot
environment.
But, be careful, as you’re now in an actual root environment on your computer, so any changes you make will persist after a restart
I strongly suspect this is some kind of hard drive failure, so please also provide the output for:
fdisk --list
and
cat /etc/fstab
…from the chroot
environment.
