After reboot, "You need to load the Kernel first" over and over again

When I reboot my computer, it says:

error: couldn't read file
error: you need to load the kernel first

Press any key to continue...

When I press a key to continue, it brings me to a boot menu, which has "Ubuntu" and "Advanced options for Ubuntu." When I click enter to choose Ubuntu, it just brings me back to the error screen.

I opened the Grub prompt and typed "reboot." When it rebooted, it brought me back to the error screen.

Eventually, I am able to boot it, but it happens frequently and it takes a really long time to get it to work.

Any fixes?

Ubuntu 20.04.2 LTS

Solution 1:

I have been facing the same issue for far too long right now and nothing seemed to work until I found this forum. There seems to be an issue

related to some patches around TPM (Trusted Platform Module), where it fails to perform some sort of tracing.

As discussed in the last comment in the forum, your machine might not have a TPM, but instead have its successor Intel® Platform Trust Technology (Intel® PTT), which could be the root of the issue.

Running the following commands solved the problem for me (unloading the TPM module):

sudo cp /etc/grub.d/40_custom /etc/grub.d/06_notpm
sudo bash -c 'echo "rmmod tpm" >> /etc/grub.d/06_notpm'
sudo update-grub
