I use Fedora 20. After pressing ctrl-alt-some function key, I entered emergency mode. Now every time I boot my computer, I enter emergency mode before I enter the normal OS. When I enter the normal OS there are no problems. How do I disable the auto-boot into emergency mode?

Hi,

Are you able to get to the bootloader, or is that foobar too? I am not sure what button you pushed but I think that we can get this fixed.

I would start with this option from askfedora, Fedora 19 is always booting into emergency mode

I tried this, but I ran into an issue: When I tried to boot into the live USB, it would give the error that it could not load the ext4 module

OK, I did the check with the gparted live cd. Nothing changed. May I also add that nothing is not working other than that whenever I boot I have to press ctrl+d, and it worries me. There are no other symptoms. It is really odd.

Please be patient, what you have to remember is that all of us are volunteers and work full time, so can only answer when we have spare time. Also we're not necessarily on the same time zone.


I did a quick google and found these recent posts:

Fedora 20 boots in emergency mode - Unix & Linux Stack Exchange

https://ask.fedoraproject.org/en/que...?comment=29219

If none of the above work, can you load into fedora and copy and paste the output of the following files:

sudo blkid

(you may have to run the above as su and root password)

cat /etc/fstab


cat /boot/grub/grub.cfg

Above are the menu entries that you will see when grub2 boots. The rescue system is possibly the first stanza to be loaded as the menu order in grub2 is controlled elsewhere.

Before I suggest an action, how do you boot Fedora normally?
Are you having to boot into the emergency or rescue system and then reboot or are you
pressing up arrow at grub 2 to highlight the Fedora, with Linux 3.15 entry and then press enter?

1) Press power button
2) Press enter on the already selected Fedora, with Linux 3.15 (it is the top item)
3) Fedora splash screen with the Fedora logo "loading"
4) It immediately enters emergency mode
5) I press ctrl+d and then Fedora starts like normal

Have a look at this post:

https://www.techsupportforum.com/foru...te=1&p=5434673

Try running

journalctl -cb

from a terminal and see if any errors are displayed. Looks like a few people have had this on the Fedora Forum, a few have solved it and others havent.

What key combo did you press that caused this error and were you at the terminal or grub screen or somewhere else when you pressed it?

[[email protected] home]# journalctl -cb
Failed to seek to cursor: Invalid argument

I do not know the key combo, it was an accident. It took me to the terminal.

Tyr omitting the c switch, on my Fedora 20, I can only get output when I type journalctl -b

Or use journalctl -xb this will add a explanation to the ouput, might be easier to decipher.

Thanks for correcting me, I should have typed -xb and good to know that Alpenadiver also uses Fedora 20 :)

journalctl -xb works, but is ~1000000000000000000000000000000000000000000000000000000000 lines long. So what am I looking for?

To cut down on the size of the log, try the following filter based on time. If you have started Fedora today, try
journalctl --since=today

This will cut the log down hopefully to a more manageable size. I ran it after booting up my laptop, and it was 190 lines. Much easier to look through.
