I had the same problem with my UEFI bios machine and I fixed it so for Centos 7:

1. Boot from an rescue linux usb

2. When the rescue system is running:

2.1) #chroot /mnt/sysimage

3. Config network:

3.1) # ip addr add X.X.X.X/X dev X

3.2) # ip route add default via X.X.X.X    <--- default router

4. And finally:

#yum downgrade shim* grub2* mokutil

#exit

#reboot

I hope you can fix it with these steps.

Thanks for the detailed suggestion.

Unfortunately I couldn't recover the installation, and I had to redo everything from scratch, which cost me the first two days of my holidays.

One thought regularly kept crossing my mind:

"How on earth could this have passed Q & A ?"

:o)

Cheers,
