I installed the latest Ubuntu "20.04 LTS" on my machine, the installation was successfully and without any error.
The problem is that after the installation when the system starts, during the boot I get this error message "You need to load the kernel first" after the grub.
This error message seems to appear randomically, more often when I do a reboot using sudo reboot now or halt --reboot or rebooting via GUI and when the system is shutted down and I start it normally pressing the power button. Other times the system boots normally and the OS is ok, I can use it and there are no issue.
- Tried different times reinstalling the OS re-downloading the ubuntu image and using different tools in order to create the botable key (rufus, dd, balena etcher, ubuntu disk creator).
- Tried to reinstall the system using no network and disabling thirdy part additional components.
I'm on a Dell Inspiron and secure boot is disabled and the system is not a dual boot, there's only one ssd with a single instance of Ubuntu installed on it.

Tell me if you need other infos about the OS or the HW.
EDIT
If someone is still interested I still want to share info about this.
I didn't found a way to fix the error so I tried to reinstall the OS being sure of using UEFI mode, I followed the official guide by dell, but after the installation process the error was still present. The only way I found to fix the error is entering the BIOS and selecting my nvme as first boot option, disabling the entry relative to ubuntu. Don't ask ehy, I don't know, but now I'm using the system without troubles for months.
