[Errors] You need to load the kernal first

[Rhaom]

Hello,

I am pretty new to Kubuntu but I have some experience with Manjaro and Red Hat, I am running a Dell Inspiron 3793 which is a fairly average laptop.

What appears to be randomly, when I boot my laptop sometimes it boots just fine and other times it will tell me "You must boot your kernal first" then take me into grub, if i reboot my computer and go into the bios and tell my system to boot from the ubuntu partition this fixes the problem 99% of the time, sometimes however I need to power off my system, wait a few minutes and then turn it back on and it will then boot up just fine.

I would appreciate if anyone could assist me with solving this issue

I assume that you dual boot with another distro?
If so then, you probably need to update grub on one OS after there has been a kernel update the other OS. There have been many security fixes lately, so there have been more kernel u[pdates than usual I think. At least for 20.04.

Each OS has its own boot loader (the Grub boot loader in this case), so when there is a change on one (usually a kernel update) the other boot loader does not know about the new setup, so you have to also update grub on the other one.
If this is the case, it is not specific to (K)Ubuntu.

I was previously running Manjaro but I thought I had cleaned out all partitions on both drives prior to moving to Kubuntu, I had not even spotted that!

Assuming I just wipe the sda2 partition and update grub it should all be ok?

Thanks
