My computer froze and I foolishly did a hard reset. Now when I try to boot Ubuntu, it stalls on the loading screen for about 30 seconds and then kicks me into emergency mode. I've taken a look at the journal and I'd gladly post the revelant results here but there are hundreds of lines and I'm not sure which parts to post. I'll update this if/when someone guides me to it.

Thanks. :)


here are some highlighted/red sections that seemed like they'd be relevant:

secureboot: Secure boot could not be determined (mode 0)

ACPI BIOS Warning (bug): Optiional FADT field Pm2ControlBlock has valid Length but zero address: (long string)

xhci_hcd 0000:4:00.0: host halt failed, -110

|| : can't setup: -110
|| : init 0000:4:00.0 fail, -110
Timed out waiting for device on dev-disk-by\(long string).device.

  • Please execute the command journalctl -b -p 3, and paste the output of that command into your question. – Charles Green Apr 1 at 17:26

Lets first check your file system for errors.

For 17.10 or older...

  • boot to the GRUB menu
  • choose Advanced Options
  • choose Recovery mode
  • choose Root access
  • at the # prompt, type sudo fsck -f /
  • repeat the fsck command if there were errors
  • type reboot

For 18.04 or newer...

  • boot to a Ubuntu Live DVD/USB
  • open a terminal window
  • type sudo fdisk -l
  • identify the /dev/XXXX device name for your "Linux Filesystem"
  • type sudo fsck -f /dev/XXXX # replacing XXXX with the number you found earlier
  • repeat the fsck command if there were errors
  • type reboot
