 Posted: Wed Jan 31, 2024 2:42 am Post subject: [SOLVED]What have I done, Grub not displaying new Kernel? |
 |
|
[SOLVED] See my reply below for details of what I had done wrong and how I ended up fixing it.
Hello
Upgraded the kernel this morning, got home before and ran
| Code: | | grub-mkconfig -o /boot/grub.cfg |
The command runs fine but on reboot the new kernel doesn't appear in the list, Grub is displayed but the list of available kernels hasn't changed.
I suspect its something to do with efi? Not sure what I've done here, i'll post below information I think will be helpful. Thank you.... Again.

That should be grub-mkconfig -o /boot/grub/grub.cfg. Did you really write it like that?

I'm guessing /dev/nvme1n1p1 is your intended /boot and /dev/nvme1n1p2 is your intended swap. If so, /boot is not mounted, and your swap is not activated.
It does no good to run grub.mkconfig when /boot, where it needs to write to, is not mounted.
/etc/fstab may not be what you intend. |

It was all of above, fstab wasn't configued. /dev/nvme1n1p1 was not mounted and I had grub booting off my USB somehow.
Configured the fstab
mounted the /efi
Installed Grub
Generated Grub config using "grub-mkconfig -o /boot/grub/grub.cfg"
Although, I have now installed grub to a few locations and cant be certain which is in the correct place  ill have to clean that up but otherwise everything is working. I now have the lastest Kernel with working Wifi and offical Nvidia drivers working! Happy for the time being, ill clean up the mess I've made with Grub later. |
