F25 (4.8.12.300) wont boot after update!

I get this screen ----> http://imgur.com/HB93aaR when trying to boot after updating F25. I while booted into Fedora, I selected "install updates and restart" after it restarted it tossed me into that screen. I'm not entirely sure where this is in the boot process but I'm guessing it's grub failing to load properly?

I have it dual booted with windows so when I turn on my computer, bios asks me which operating system I want to select, I've tried selecting all three options for Fedora (4.8.12-300, 4.8.6-300, and 0-rescue-aff1f79b....) none of which work they all take me to the same screen.

I'm really lost here. Not even sure where to start outside of reinstalling the entire OS which is obviously not ideal. Any Ideas on how to go about troubleshooting this? THANKS!

I also updated my GPU from a gtx 960 to a gtx 1060 however I am almost positive this error was occurring before the hardware upgrade. Not to mention if I had the GPU installed before the error occurred I booted right into Fedora, saw there were updates that needed installing, updated and restarted and THEN got stuck where I'm at.

Does the system boot with a older kernel?

I'd suspect something went wrong with the hardware install. Do you still have your old gfx card? If so - can you take the new one out, put the old one back, then try to boot?

You might also re-seat the memory - and generally check for anything out of the ordinary...

Windows boots fine, detects the memory and the gpu. Ill give it a shot though.

You just did the update today?

The recent kernel revision isn't 4.8.12.300... It's 4.8.15-300. So... You can't boot any kernel installed... You will need to boot from media, mount the install, and chroot to the install. You'll then need to:

  • Take a look at your grub.conf (then optionally)
  • run depmod (-or-)
  • dnf reinstall kernel

F25 is so broken. I see 3 posts a day about Fedora not booting after kernel update. Happens to me also. I just use the original kernal from the original install and do dnf -x kernel* update. For some reason the devs don't care. Come back tomorrow and see more posts about Fedora not booting after kernel updates...
