Restoring Grub when Distro hopping
I have adopted Ubuntu as my Primary operating system, but I also enjoy trying out different distributions in a separate partition. When trying a new distribution, my Ubuntu Grub2 is then overwritten with a new Grub or Grub2 install and I end up with the a temporary partition, holding the Grub configuration. This is usually not a problem, but just seems "wrong" to me. Worst case, I just install Ubuntu over the linux experiment to get a familiar Grub2 back in a temporary partition. Is there an easy way to just restore my original Ubuntu Grub2 and force it to discover the new experimental linux partition as if it was a fresh install?
