So it was an update that did this?

Had to be, as it was working. I shutdown to go home. Then it wasn't working.

jmoore

@JaredBusch Ok thanks, good to know.

Unless someone has any more ideas, I'm also out of ideas and I will have to reinstall since I will need my laptop on Wednesday and Thursday.

Kernel 5.3.12-300 is current.
But both previous kernels fail also.
5.3.11-300
5.3.8-300

So this suggests that a library or something has failed, not the kernel. That's going to be a huge pain.

Right sounds like the grub update borked itself.

Can't provide any input but it's interesting to read the problems that shows up every time there is a new Fedora release out. Your customers are a forgiving bunch for sure.

That said, it's great for the open source community to have lots of people running the latest and greatest.

I've been on Fedora about 2 years on my laptop now and I know exactly what you're talking about.

No new release issues on any Fedora system that I use, either. Been flawless and we use it across laptops, desktops, and servers.

I did have a Fedora 31 laptop (different model Dell than mine) spun up and logged in two weeks ago. I have ran updates on that one and rebooted. it is running fine.

Yeah, my Dell with F31 hasn't had an issue yet and I keep it updated.

@JaredBusch said in Fedora 31 stuck in a boot loop:

The updates show that grub had changes. Shit happens with all OS.

They also showed that something new was being compiled against GLibC and the Kernel.

That's definitely my guess.

@JaredBusch have you tried the boot loader rebuild process listed here?

I don't have any internet. It only boots to emergency mode when I choose the rescue kernel. Anything else is the boot loop.

What about booting to a rescue USB stick?

I can boot to a live USB. try it from there you think?

managed to boot into recovery mode and get an IP from a USB ethernet dongle.

I ran through the instructions fine on that link, but then step 5 was a link to another page that stated to run grub2-install /dev/sda

Well that puked on the nowEFI thing. Google told me I needed to dnf install grub2-efi-x64-modules.

Now it dies and says grub2-install: error: cannot find EFI directory

These look to be more up to date with more details.

Now I am trying to boot up and it simply goes back to bios.
Obviously something is crashing in the boot cycle. But what?
Kernel 5.3.12-300 is current.

I dont know why you love that Distro at ML ... Ubuntu 19.10 and POP OS looks similar in software updates and more stable

That's not helpful for his situation.

well, I totally broke something in grub. Laptop no longer sees any boot partition.

So, clean reinstall time.

Just really annoyed that I couldn't figure this out with everyone's help.
