I have an Acer computer that came with Microsoft 10 but I installed Linux Red Hat as my operating system which I used exclusively. I suffered a power surge and now when I try to boot the operating system, I receive several error messages and am left in emergency mode.
How can I get out of emergency mode and back into my computer?

G'day @ebunch and welcome to linux.org, albeit under trying circumstances :)

I may not be the one to help you, but a couple of questions -

  1. How are you communicating with us?
  2. Can you post eg phone pics or other information?
  3. Describe the emergency mode, including any prompt
  4. Do you have a support agreement with Red Hat, and which version?
The more you tell us, the better we may be able to assist.

Cheers

IF you don't have hardware problems due to the surge, try logging in (in emergency mode) and entering "systemctl default" and reboot. That was needed with CentOS, so I assume it's the same with RHEL.

However, that's a guess - 'cause I don't know what your error messages are. As Wizard said, we need to know what specific errors we're working with.

I've had a power surge or two but my tower running Linux Mint just boots back up,so I can't help you.
My computer is plugged into a power surge protection board which might be why no damage is done. ;)
Your computer my have suffered damage that can't be fixed,I might be wrong but a small amount of static electricity can kill computer components. I always keep an Image of my Operating System on an External HDD for times just like this, so I don't loose everything and have to reinstall the OS. ;)

Entering emergency mode. bit the shell to continue. Type "Journalctl" to view system logs. You might want to save run/initrons/ednokreport.txt to a USB stick or Moot after mounting them and attach it to a bug report.
I do not have any agreement with Red Hat
I hope will this info you can give me direction. Thank you.

G'day Liz, just a holding post for now. :)


I have only had the quickest read of the above so far. I have some time up my sleeve this arvo (Aussie time), and I will digest it and see if I can help.

I see my fellow Aussie Brian @Condobloke has put a like on your Post too, which reflects that you have given us some good information under trying circumstances.

We'll see if we can get you sorted. Back as soon as I can. ;)

Cheers

Wizard
BTW you can call me Chris, Wizard, Wiz - anything but late for dinner.

BTW 2 - if you can tell us your timezone, I can try to work with that.

Thanks, Chris.
I'm in the Eastern Time zone.
Thanks for your help!

@ebunch I can't help you with your problem but I can tell you how to protect your computer from power surges. Before I did what I'm gonna suggest to you, I had 4 motherboards fried in less than a year.
So, look for the brand Brennenstuhl - it's made in Germany and its primary purpose is exactly that: power surges protection.
First you get this and plug it into the wall plug. Then you get this by the same brand and plug it into the silver thingy. My silver thingy is pretty much the same, only mine has no screen or buttons. Sorry for the "this" and "this" words, it's just that English ain't my native language and I have no idea what these items are called in English.
With this double protection you'll forget what a power surge is, believe me! I got my things in 2015 and I'm very happy with their functioning - no more fried motherboards, no more screwed up operating system!

It's a surge protector.

@ebunch, if you live in the Eastern United States, you may want to look for an American style plugin on your surge protector.

Before the disastre have you create un timeshift? a backup system? If yes at bootstrap you have
the alternative to repair the SO...If NO....reinstall it!

Seeing the content of "/run/Instramfs/rdsosreport.txt" might be helpful.

Try doing the following:
1. Boot from centos dvd.
2. Select Troubleshooting from the boot menu.
3. Select Rescue a Centos System.
4. Select continue
5. chroot /mnt/sysimage
If this does work we could try to continue from there, however I doubt it will work since my guess is your partitions are probably screwed or some other hardware problem like @KGIII already mentioned. If that doesn't work go through steps 1 through 3 again, and then this time instead of selecting Continue select 3(Skip to Shell), from there try the following.
Code:
fdisk -l
lsblk
What happens?
