I have a Dell Precision T7910 Workstation with no other OS in it, the power went down in the whole city while the workstation was on, after the power came back I tried turning on the workstation but I get into emergency mode with the error:

systemd[1]: Failed to start Load Kernel Modules.
FAT-fs (sda1): IO charset iso8859-1 not found
Welcome to emergency mode! After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or ^D to
try again to boot into default mode.
Press Enter for maintenance

After pressing Enter, I'm logged in as root without typing a password (WTF Ubuntu? Seriously?)

  • System boot is set to UEFI.
  • /dev/sda is a 256GB SSD
    • /dev/sda1 is /boot/efi (vsfat)
    • /dev/sda2 is / (ext4)
  • /dev/sdb is a 1TB HDD
    • /dev/sdb1 is the swap partition
    • /dev/sdb2 is /home (ext4)

A simple fsck /dev/sda1 doesn't show any errors.

I can't boot from a live USB neither in UEFI mode, nor in Legacy mode. (USB stick does boot in other systems)

If I try to boot in Legacy mode I get the following error:

error: unknown filesystem.
Entering rescue mode...
grub rescue>

Any help is greatly appreciated.

Solution by OP:

So I was installing some texlive-* packages when the outage hit, I tried booting from a previous kernel and it worked, after rebooting everything is normal again
