Re: [PLUG] Swapping motherboards

["Gavin W. Burris" <bug@wharton.upenn.edu>]

Hello, Eric.

You'll want to boot from the install media into rescue mode.  That will give a root prompt with the on-disk system mounted under the /mnt/sysimage/ directory.  You should then be able to run something like:

# chroot /mnt/sysimage/
# grub2-install

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/sect-rescue-mode.html#sect-rescue-reinstall-grub2

Cheers.
