I can't boot my Debian 9.5 with following errors. If I remember correctly ACPI Errors were shown every time I turn on PC. But computer always boot right with these errors, so I didn't care much. The new error starts at "A start job is running.."

error 1st part

error 2nd part

When did the error start? I was going to sell my older HDD so I erased the disk /dev/sdd via command dd if=/dev/zero of=/dev/sdd bs=1M. The disk was mounted to /diskB_1TB. After erasing the HDD I turned down computer and then disconnected the disk from a motherboard. After that I turned on the computer but the error occured for the first time.

I've tried procedure from: https://askubuntu.com/questions/924170/error-on-ubuntu-boot-up-recovering-journal/924335?noredirect=1#comment1512824_924335 but it fixed nothing.

tried commands

I have 4 disks

  • /dev/sda with windows
  • /dev/sdb with linux debian
  • /dev/sdc as 2TB data disk
  • /dev/sdd as 1TB data disk (the former disk I erased and disconnected)

my disks

Is there anything I can still do in this situation? I'm pretty sure I did delete only /dev/sdd disk. I can still access data (via terminal) located in /dev/sdc and in /deb/sdb where my /home/stepaiv3 is located. Moreover I can normally boot into my windows on /dev/sda.


Systemd assumes certain mounts are critical to the system and as such a failure to mount one results in it switching to emergency mode.

Systemd should have reconfigured its automount units when the device was disconnected unless it appears in /etc/fstab or you configured it as a mount unit. So the issue is likely that you still have /diskB_1TB in your fstab.

From your emergency mode console try editing your fstab /etc/fstab and remove the line with /diskB_1TB then reboot.

  • Wow.... it was that easy! :D Thank you so much. After removing the line from /etc/fstab my Debian boot :) – kocourOggy Oct 9 '18 at 0:07
  • Good call. The bigger problem is that often this issue is not logged at all. – Rui F Ribeiro Oct 9 '18 at 1:46
