Yes, I have tried that multiple times, both from Troubleshooting Mode
(booting using CentOS 7 Installation CD) and from within the actual
system (booted using super-grub2 disk).
I always get (from troubleshooting mode):
# grub2-install --root-directory=/mnt/sysimage/ /dev/vda
Installing for i386-pc platform.
grub2-install: error: unknown filesystem.
or (from within the OS):
# grub2-install /dev/vda
Installing for i386-pc platform.
grub2-install: error: unknown filesystem.
How can I fix that?
