Grub boots from kernels that I removed

I'm running Fedora 26, rpm -qa kernel outputs kernel-4.13.5-200.fc26.x86_64. And that's the one I want.

enter image description here

I had 3 kernels showing in grub, that one, and 2 newer ones, Wifi wasn't working when booting from the other two so I excluded kernel updates from dnf, and I removed the newer kernels sudo dnf remove kernel-4.x.

All went smoothly, however when I restart, I still can see them in grub and I can boot from them and the wifi won't work if I pick them.

Here I am booting from the newest kernel that I removed.

Here's my grub

What went wrong?

You can set your default entry without removing the newest kernel through grub2-set-default command. In your case without updating grub2 use:

grub2-set-default 2

After grub update you should have tow kernel on your grub 2 configuration file the command should be (the first kernel is 0 the second one is 1):

grub2-mkconfig -o /boot/grub2/grub.cfg
grub2-set-default 1

The command :

# awk -F' '$1=="menuentry " print i++ " : " $2' /etc/grub2.cfg

will print the exact order of the existing kernel on the grub.cfg file.

Look in /var/lib/initramfs-tools/ if the newer kernel-versions are present.

Erase them, also in /boot relevant entries, like vmlinuz initrid and System.map. But be carefull, that you don't delete the false one!!

Your answer is wrong . Reason: Question is tagged "fedora" but Fedora does not have an "update-grub" command. This is only found on Ubuntu and some other deb-based Linux distros. And /var/lib/initramfs-tools/ is also only found on deb based distros.
