I have been using Zorin OS 15.2 for over 2 weeks. It's been working fine without any problems at all until today when I switched on my laptop it booted into emergency mode. The journalctl -xb command gave me this log:


I have pretty much no idea what went wrong, I don't remember doing anything that would have caused my OS to boot into emergency mode.

Things I have tried to fix this:

  1. Used a live USB, in the terminal I ran a fsck check on my Zorin OS partition, it showed there was some error but it fixed it anyway. When I tried booting after this it still loads into emergency mode.

  2. I was having certain PCIe Bus errors shown in the log files. It was written:

FADT declares the system doesn't support PCIe ASPM, so I disable it

I tried the solutions given in this site:


where I disabled the ASPM by editing the /etc/default/grub file into this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off" And yet the problem still persists as it still boots into emergency mode.

NOTE: The log text in the pastebin url that I have given above is after I booted into emergency mode after setting the pcie_aspm to off as I said above.

Please help me out here as I don't know what to do next to have my OS running up again.

P.S: I went to recovery mode to run fsck check but for some reason, I was not able to go up or down and my keyboard inputs were not working or responded only after I kept pressing a key for a long time. That's why I created a live USB and did fsck check from there.

Laptop Info:

Acer Nitro 7

My OS was installed in partition: /dev/nvme1n1p2

I have dual booted my laptop with Windows in /dev/nvme0n1p1 and another NTFS partition in /dev/nvme0n1p2

UPDATE: When I went to /etc/fstab, this is what it showed:

# /etc/fstab: static file system information.
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

/swapfile   none    swap    sw  0   0

UUID=D4C7-8EDC  /boot/efi   vfat    defaults    0   1

but when I ran blkid, the output was:

/dev/nvme0n1p1: UUID="0B40D97D7E09A62B" TYPE="ntfs" PTTYPE="dos" PARTLABEL="windows" PARTUUID="30dc3ca6-e51f-43f5-ac5e-fd752f8ac23a"

/dev/sda1: LABEL="ZORIN OS 15" UUID="C414-F2D2" TYPE="vfat" PARTUUID="00141c12-01"
/dev/loop0: TYPE="squashfs"

I noticed that the UUID of my partition nvme0n1p2 is different in the above 2 outputs. I remembered that I had formatted this partition yesterday and stored some files in it. Could this be the reason why my OS is booting into emergency mode?

Luckily got my OS working again. Apparently a change in UUID in any partitions that is visible to the OS can lead to the OS booting into emergency mode. All I had to do was:

  • enter blkid
  • Take note of all the UUIDs in every partition.
  • And now enter cat /etc/fstab. In my case the UUID of partition "nvme0n1p2" was different from what it had showed in blkid.
  • So, all I had to do was: sudo nano /etc/fstab
  • change the UUID of the partition to whatever UUID blkid showed.
  • Now enter reboot

NOTE: The above method is for doing it from the emergency mode itself (after pressing enter). You can also use a live USB, mount the particular OS partition and do the same steps.
