The problem is that on some older nodes, the uefi implementation in the firmware seems to have a limited in memory size for the efivars. As since shim v12-2, we enrolled two certificates (previous one and new one) to allow booting on previous grub2/kernel while also permitting booting the new grub2/kernel pkgs, (signed with the new key), the size of efivars grew, but that wasn't considered a critical error by shim on buggy/older firwmare. If secureboot wasn't enabled (the case on such old imac - even on newer ones btw - ) it was still loading grub2 and so machine was booting. With the rebase to shim v15, that check is now considered critical (as shown in the message with MokListRT) and so shim doesn't allow to boot grub2. Workaround #1 : on existing machine, before updating, be sure to exclude shim* and mokutil* (so that it can stay at version shim-x64-12-2.el7.x86_64 echo 'exclude=shim*,mokutil*' >> /etc/yum.conf yum update Workaround #2 : if you have already updated and also rebooted, you have to use a live media to - mount /boot/efi - enter $mount_path to go to /boot/efi/EFI/centos - cp grubx64.efi over shimx64.efi - umount - reboot We can , as shown in workaround #2, boot directly into grub2 as SecureBoot isn't even possible on the iMac, so bypassing shim completely. |

The same happens on Dell PowerEdge R410 with UEFI firmware version 1.14.0 (which is the latest provided by Dell). |
|
|
don't know the memory size allowed by Dell for efivars, but you should be able to get back in action with previous shim at least (assuming that you have SecureBoot enabled, in which case you need shim and can't boot straight to grubx64.efi). |
|
|
Happens on IBM System x3630 M3, but you can go into Setup, and choose Boot From File, then navigate in the tree to grubx64.efi and boot from it. I'm still to test with latest UEFI firmware. |

@arrfab: That's right, downgrading shim-x64 to 12-2 helped. SecureBoot is disabled here, so, yeah, directly booting grubx64.efi would have worked, too. |

I have this error on a MacBook Pro (Retina, 13-inch, Early 2015) after upgrading as well. I dual boot with the original version of OS X (10.10) that came with the system so I guess I have an older uefi firmware. I tried the 'cp grubx64.efi shimx64.efi ' trick but it didn't work, I get the same error message when I try to boot CentOS. I assume this is because secure boot is enabled. Will it work to manually copy files into /boot/efi/EFI/centos from the shim-x64 12-2 package? Is there something else I can try? Thanks in advance for your help. |

@benkonrath : yes, you can extract shimx64.efi from previous shim-x64, or you can also downgrade to shim-x64 (and mokutil) and then exclude shim*,mokutil* from yum Or you can extract the shimx64.efi from the downloaded pkg, use "rpm2cpio ...|cpio -ivdm" to retrieve it and overwrite the one in /boot/efi/EFI/centos path Thanks for the report, but one thing that I wasn't aware of was that SecureBoot was a possible thing on Apple hardware, nor then that it was enrolling Microsoft keys by default |

I have the same issue after upgrading CentOS 7 on a Dell R210 server. BIOS: 1.10.0. Server powers up, runs in to this error when trying to boot UEFI and then powers down.

@arrfab Copying the files from shim-x64 12.-2 to the EFI partition worked. I was able to do it in OS X with the help of rEFInd (used to mount the EFI partition) and The Unarchiver (used to unpack the rpm). Now that I'm back in CentOS, I've downgraded shim-x64 and mokutil and I excluded them from updating. I'm not actually sure about SecureBoot being enabled on the MacBook Pro. I was only guessing since booting directly with grubx64.efi didn't work. Thanks for the help on this. |

I have the same issue on IBM System x3650 M3. Thanks to @eduardok I managed to boot the computer with selecting grubx64.efi. |

Confirming same issue as Splash (in c33222) but on a Dell R410. Oddly, one Dell R410 *doesn't* have the issue, while its twin server *does*. We only noticed after swapping the disks in the RAID set between machines due to a hardware failure on the original server. Nothing worked except copying CENTOS\GRUBX64.EFI over top of EFI\BOOTX64.EFI - still unsure why that is, but that's the step that finally allowed it to boot unattended. |

Same thing happened to me today. Upgraded an IBM x3550 M3 from 7.5 to 7.6 online. Didn't come up again. I found the Failed to set MokListRT: Invalid Parameter error on the console. Booting from the installation DVD got the same error. Don't think this server even supports secure boot, couldn't find any mention of it in the BIOS setup, but has UEFI. In the end I wiped the machine and installed CentOS 6.10. Reason is this is an old unused machine and might be retired any day. The users are much more likely to want a CentOS 6 server if one of the other servers breaks down. If I had found this page earlier I would have tried overwriting the EFI file as suggested above. I'll bookmark this thread for site documentation in the very unlikely case someone wants to run CentOS 7 on it in future. |

So, thanks to @puiterwijk , we have now a patch and also a PR upstream (https://github.com/rhboot/shim/pull/157) Before we ask Microsoft to sign our newly built shim, we'd like to have some people to test our interim build (the shim, unsigned) As it doens't affect people with UEFI *without* secureboot, it should fix your issue (it works on my old iMac, the only node on which I can test this ...) Can you just test this and report feedback please ? (if you still have access to the running node) rpm -Uvh https://people.centos.org/arrfab/shim/results/shim/20181206092329/15-2.el7.centos.x86_64/shim-unsigned-x64-15-2.el7.centos.x86_64.rpm cp /usr/share/shim/x64-15-2.el7.centos/shimx64.efi /boot/efi/EFI/centos/ Then reboot and it should boot on shim 15, with the added patch, would still displays the MokListRT issue, but wouldn't consider that a fatal error, and so would still move to grub2 (and so booting normally) Thanks for your feedback ! the more answers we'll get, the faster we'll submit to microsoft for signing |

I can confirm that shim-unsigned-x64-15-2.el7.centos successfully boots on our Dell PowerEdge R410. |

I can confirm that shim-unsigned-x64-15-2.el7.centos.x86_64 successfully boots on a IBM System x3650 M3 with UEFI 1.20 and without Secure Boot after copying test shim manually: cp /usr/share/shim/x64-15-2.el7.centos/shimx64.efi /boot/efi/EFI/centos/shim.efi (i.e. destination file name was shim.efi not shimx64.efi) I still see the error message for a very short time but the system continues to load grub and boots fine. Thanks! |

I came into the same issue on a System x3250 M3 I booted as suggested from File then downgraded to those packages mokutil-12-2.el7.x86_64.rpm shim-unsigned-ia32-12-2.el7.x86_64.rpm shim-unsigned-x64-12-2.el7.x86_64.rpm shim-x64-12-2.el7.x86_64.rpm Rebooted and all went fine . So I can now just go on holidays and not be called for old servers not booting anymore ... |

How does it choose which EFI image to boot? I rebooted after running "rpm -Uvh https://people.centos.org/arrfab/shim/results/shim/20181206092329/15-2.el7.centos.x86_64/shim-unsigned-x64-15-2.el7.centos.x86_64.rpm ; cp /usr/share/shim/x64-15-2.el7.centos/shimx64.efi /boot/efi/EFI/centos/" yet it powered off (booted the wrong efi instead of shimx64.efi). I had to manually boot from file shimx64.efi, which indeed printed the message like you said, but at least booted. |
|
|
@eduardok The command "efibootmgr -v" will show you the path/filename for each EFI boot target. |
|
|
@eduardok : basically if you overwrite shimx64.efi with the cp command, it's the default entry for centos install, so it should reboot on that one. The fact that you selected it directly as boot entry and that it worked is also what I wanted to get as feedback |

MacMini here, disk encrypted, replacing shimx64.efi with the one from the shim-unsigned-x64-15-2.el7.centos.x86_64.rpm fixed the issue. Same issue after a yum update happened here and being a bit more new to CentOS took me a little bit of extra brain power to figure out as I couldn't find /boot/efi/ folder at all on my machine. Which Im sure might be obvious to most here, it wasn't as obvious for me, and so I only provide the following in the event that someone else out there might be as clueless as me. Booted off a CentOS USB Installer I made when I first setup the system and chose the Troubleshooting menu option and then the Rescue option. From there I said Continue which then asked me for my HDD password, and mounted it under /mnt/sysimage. I chrooted that directory as the screen gave direction for and then I was able to get to /boot/efi/EFI/centos/ as advised above. Unfortunately, I couldn't just download the rpm file posted above as I don't think the computer had DNS or Internet setup on it while in this recovery mode, so I downloaded the file on my personal computer and stuck it onto a USB drive and mounted that drive on the centos system (mount -t vfat /dev/sdc1 /mnt/usbdisk/) I copied that file to the CentOS system and then ran rpm -Uvh /home/user/shim-unsigned-x64-15-2.el7.centos.x86_64.rpm then did cp /usr/share/shim/x64-15-2.el7.centos/shimx64.efi /boot/efi/EFI/centos/ typed exit to get out of the chroot then shutdown -r now the restart came up with a lot of stuff on the screen, errors and warnings and then restarted again all on its own. The 2nd restart it booted up just fine without any issue at all. |

I can confirm that shim-unsigned-x64-15-2.el7.centos successfully boots on our Dell PowerEdge R410 thanks! |

I can confirm that shimx64.efi from shim-unsigned-x64-15-2.el7.centos successfully boots on our Dell PowerEdge R310. Secure boot is not available on this server. Thanks for the quick fix. |
|

Thanks for the feedback. I launched a CI validation test against that build to test Secureboot validation : https://ci.centos.org/job/CentOS_7_SecureBoot_validation_SelfSigned/20/console It's now waiting for Review and then Microsoft can sign the shim again and we can then sign/push to updates https://github.com/rhboot/shim-review/issues/45 |

Hi, I only wanted to report that I have here 2 identical machines (x3650 M3). On both I apply shim-unsigned-x64-15-2.el7.centos. One starts now fine but the second one hangs on exactly that screen with the message: Failed to set MokListRT: Invalid Parameter Something as gone seriously wrong: import_mok_state() failed: Did you have any idea why this is happen? Selecting grubx64.efi works... |
|
|
@jb_alvarado : if you're sure that you have indeed copied/overwritten the shimx64.efi on that system with the one from shim-unsigned pkg, it should boot. Can you ensure that such node is configured to boot on that file ? efibootmgr -v And then sha256sum /boot/efi/EFI/centos/shimx64.efi |
