Grub-core error "you need to load the kernel first"

Hi there, after two years with Ubuntu I decided it is time to change and Fedora looks like a nice choice. Unfortunately my first experience with system is kinda worse.

I downloaded Fedora workstation, made bootable flash drive, run system from flash drive and started installer. In installation destination I chose my only disk with automatic patitions configuration. I reclaimed space by removing all original partitions. Installation run without any problems and when finished prompted me to reboot. So far so good. Problem is that system have never booted.

This is what I get on every start:

error: …/…/grub-core/commands/efi/tpm.c:148:Unknown TPM error.
error: …/…/grub-core/commands/efi/tpm.c:148:Unknown TPM error.
error: …/…/grub-core/commands/efi/tpm.c:148:Unknown TPM error.
error: …/…/grub-core/commands/efi/tpm.c:148:Unknown TPM error.
error: …/…/grub-core/commands/efi/tpm.c:148:Unknown TPM error.
error: …/…/grub-core/loader/i386/efi/linux.c:208:you need to load the kernel first.

The only thing I can is to play with some grub command line. So my question is obvious. How can I run Fedora?


According to the above:

  1. Can you check if you can disable TPM in your System Firmware?
  • also update System Firmware if possible
  1. If the above do not help, try to remove TPM from grub
  • When seeing the grub menu, choose edit, then insert below as the first command
    rmmod tpm
    then choose the default entry to boot
  • if it helps, then edit the boot entry under /boot/loader/entries to include that command

Some hardware manufacturers do not support TPM functions on Linux systems, especially TPM 1.2 is not well supported and is an old standard. So, in many cases, you need to disable the functionality, as already said before.

EDIT: This book about TPM Modules can be downloaded for free:

It’s not free at Amazon, but I downloaded it from Springer a couple of months ago, so it seems to be free forever.

Thanks to both for the answer. So I tried:

  1. Disable TPM - Unfortunately BIOS doesn’t offer such an option.
  2. Disable secure boot.
  3. Update firmware - Not available such an update from Asus. There was only BIOS update which I did.
  4. Remove tmp module - “rmmod tpm” command always ends with error: ../../grub-core/commands/minicmd.c:138: no such module.
  5. Tried also install Ubuntu and Archlinux and both distros booted without problems.

Any other ideas??

In situations like this, I will:

Reinstall bootloader.

Just to add to this issue. I have a Lenovo C940 and ran into this same issue from F33 after updating the kernel (Can’t remember which one. I’ve now done a fresh install of F34 and immediately ran into this issue after the 1st system update of the kernel :frowning:

I don’t want to disable TPM and unfortunately, I’m a competent “User” of Linux for day to day and some configs but the EFI/Grub rabbit hole has been difficult to understand.

I’ve found this Bugzilla which is very close to my problem and will contact the Grub Maintainers incase they can assist and report back here.
