How to exit emergency mode and boot to default mode

Discussion
1

When I started my desktop I found this message:
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.

This is how I fixed the issue.
Log into root account by pressing enter. Then enter mount -a
to see where the error is (which line).
Then enter nano /etc/fstab. I used nano to remove
all fstab entrys by using CTRL+K and then closed
nano. I then ran sudo grub-install /dev/sda and then
ran sudo grub-update. Rebooted and was then able
to log back into Linux Mint. I believe the UUID’s had
become corrupted, will reinstall my W10 grub boot later.
Wish I had some screenshots, but just did not have the time.
All is well now though.

Maybe for future reference, it would be safer to back up the /etc/fstab file before editing it. This is a general recommendation.

Good point, I will look into that.

i’m not sure what environment the emergency mode drops a user into (busybox maybe?), but sudo cp /etc/fstab /etc/fstab.bak should do the trick as long as cp is available.
