Hello All,
updating from Centos7.3 to Centos7.4 rendered one of our laptops unbootable. 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.

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".
Greetings, J.
