Description of problem: After upgrading a Macbook Pro from Fedora 28 to 29, grub fails to boot the system. The following error message appears twice after selecting any menuentry (fedora 29 or old 28 included kernels): error:../../grub-core/kern/dl.c:431:symbol `grub_efi_allocate_pages' not found. Version-Release number of selected component (if applicable): After upgrading this Macbook Pro from fedora 28 to 29, no kernel boots any more. The upgrade completed successfully. The failure happens after rebooting the updated system. It is still possible to access the disk with a system rescue USB stick: grub.cfg looks normal. How reproducible: every time Steps to Reproduce: 1. attempt to boot the computer 2. 3. Actual results: crash. The computer has become unusable. Expected results: normal boot Additional info: Never had such a problem with any previous fedora releases
I found a way to boot the system by using a rEFInd image on a USB stick. It loads the vmlinuz and initramfs fc29 images. This shows that the system is fine after upgrading from fedora 28 to 29. It pinpoints to a grub2 issue. I tried to run `grub2-install -v /dev/sda' and it fails after copying: /boot/grub2/x86_64-efi/core.efi to /boot/efi/EFI/fedora/System/Library/CoreServices/boot.efi with this error: grub2-install: error: Can't create file: No such file or directory. Not sure what file that is. I verified that ...core.efi and ...boot.efi do exist and are identical. So, it must be something else but not sure what it is.
Created attachment 1510778 [details] rEFInd configuration file (refind_linux.conf) For those who may experience this bug, I am providing the refind configuration file that I used. This file (refind_linux.conf) needs to be located in the /boot directory. The refind boot image can be downloaded from the web. It is refind-flashdrive-0.11.4.img at this time. When booting with the USB stick, select the "EFI Boot", then "Boot vmlinuz-4...). Hit F2 and move down to the line with options. Hit return to boot. Hopefully, this is useful.
Reading the grub2 documentation, I realized that grub2-install should not be used on a UEFI system. I was able to fix this failure by booting the system with rEFInd and then doing this as root: dnf reinstall grub2-efi shim grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg dnf reinstall grub2-efi The system boots fine now.

My question on rEFInd_linux.conf: - How can I find root UUID? I tried with the ones I have in the pc grup, even all those gave me from rEFInd parted tool. I have disk partitioned with 3 parts: boot(fat) efi, and LVM with all the rest inside (home, root etc.). Thanks in advance.
I used labels. Here is how I did it on a Macboot Air: Boot with something like SystemRescueCd. Then run "lsblk" to verify what partitions you have. Then run "blkid" to see if there is a label on your boot partition. If not, do: - for ext2/3/4 file system: e2label <you_boot_partition> <your_volume_label> example: e2label /dev/sda2 macboot # this is on a hard disk partition - for fat/vfat file system: fatlabel /dev/sdb1 bootair # this is on a USB stick Run blkid again to verify that the boot partition has a label now. Then modify your refind.conf to be something like this: timeout 8 scanfor external,optical,manual also_scan_dirs +,bootair:EFI/Boot,macboot:EFI/Boot dont_scan_dirs "Linux HFS+ ESP:/EFI/BOOT","Linux HFS+ ESP:/System" scan_all_linux_kernels false menuentry genTOO { icon /EFI/refind/icons/os_linux.png volume "macboot" loader /EFI/Boot/bootx64.efi ostype Linux } You may have to change the paths to match your system configuration. Good luck!
