EM: Failed to open \EFI\BOOT\grubx64.efi - Not Found Failed to load image \EFI\BOOT\grubx64.efi: Not Found start_image() returned Not Found How could this occur because of an update and how to fix this? What I tried is booting from centos usb, chroot to /mnt/sysimage and gave command: efibootmgr --create --label CentOS --disk /dev/sda1 --loader "\EFI\centos\shim.efi" This gave no EM, but booting remains impossible. I have to say I don't know whether to try grub2 of efibootmgr commands. Any help would be very much appreciated. Greetings, J. _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos Hi Johan I remember I had a similar issue and I resolved it by copying grubx64.efi from /centos : cp /boot/efi/EFI/centos/grubx64.efi /boot/efi/EFI/BOOT regards Adrian Adrian, thanks for helping me out. That didn't fix the system. The EM has changed though, it now simply says " no bootable device".
