Failed to mount 'UUID=(uuid number)' on real boot

I wanted to test out different drivers for my Nvidia GPU

The ones I had were “video-linux” and “video-modesetting”
I installed “video-hybrid-intel-nvidia-prime” from using “Auto Install Proprietary Driver” and rebooted with everything working fine however I wasn’t happy with performance so I removed it and installed “video-nvidia”
After that I shutdown my laptop and tried to reboot it - the only thing showing was vendor and Manjaro logo and next a blank screen with a “_”

Several attempted reboots later I decided to get into BIOS to try to reinstall the system or restore it with Live USB, however I couldn’t get into BIOS showing again a blank screen and “_”. I read on a forum Acer Nitro 5 has problems with getting into BIOS with Manjaro and one solution was to hold down the power button for more than 15 seconds to boot BIOS with initial settings.

This worked so I tried to just reboot again with result being terminal:

“ERROR: Failed to mount ‘UUID=(uuid number)’ on real boot
You are now being dropped into an emergency shell.
sh: can’t access tty: job control turned off”

I didn’t know what to do here so I booted into Live USB to just reinstall.

When I did Installer showed “There are no partitions to install on” after checking devices manager my 2 hard drives weren’t there.

Things I tried(?)
With Manjaro Live USB I:

  • ran “Restore installes system settings” → It didn’t find any Linux installed on computer
  • looked for drivers with fdisk -l which only listed the Live USB
  • lsblk output

└─sda2   8:2    1             4M  0 part

With my laptop:

  • boot without either of the drives
  • swapping their places

The drives and my Manjaro install are yet to be seen, drives show up in the BIOS with Model Name and Serial Number though.

In the Grub menu
of either the regular system
or that of the live system (when you boot the ISO)
there should be a menu item that directs you to the UEFI (firmware) setup

so, you can and do get to the firmware setup?

I’m confused. :man_shrugging:

not a good strategy - in my opinion

This is confusing. It sounds like you installed the wrong video drivers. But at this stage, an easy fix with booting the live image and manjaro-chrooting in.

But now you went into your BIOS, and now you can’t see your hard drive?

When using lsblk use: lsblk -f

Well I would go back into the BIOS, figure out why you can’t see your drive. I would start with by restoring the BIOS defaults. (Do it once in your BIOS.) Make sure secure boot is disabled as well.

Sorry for the trouble, turns out my drives just failed.
