I was testing another distro and deleted it but forgot to re-install grub into the main drive with Centos 7. Now when booting the system it takes me to grub rescue since mbr is trying to boot from the deleted partition.
I set the root, prefix correctly, however, when running
insmod normal or
insmod linux i get this error message:
error: symbol 'grub_strchrnul' not found.
i can insert some other modules with no issue such as (reboot, hello, cat)
Currently I have no bootable CD or flash and trying to fix this from with in the grub rescue, is it possible and how?
