Subject: [CentOS] update to Centos7.4: Failed to open \EFI\BOOT\grubx64.efi -
Not Found
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.
Greetings, J.

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.

Hi Johan
appart from the above copy of the boot file, would you probably need
something like this:
efibootmgr -b xxxx -l EFI/BOOT/grubx64.efi
i.e. tell BOOTxxxx to use the intended boot file.
xxxx may be found out via
efibootmgr -v
BootCurrent: 0000
Timeout: 0 seconds
No BootOrder is set; firmware will attempt recovery
