similar to: Fixing grub/shim issue Centos 7

Hi all, 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 ???

Hello all-- These instructions are somewhat OK but my messed up box is the only one I've got basically to help with this problem.

One of my clients sent me a message that his CentOS server refuses to boot. So tomorrow I have to drive there to figure out what's going on. I guess there's a high probability it's the issue discussed in this thread. Simple
