It was my pleasure. You are right though. Grub is normally installed in the MBR. However, it can be installed within a partition. I started doing this when I developed a habit of installing multiple linux systems on my computers. If I got tired of one I removed it. I ran into a problem of my system not booting because the bootloader of the OS that I removed was removed from the MBR as well. So, I started installing Grub in partitions. Yet, normally, you would put grub in the MBR.
You learn quick and the above commands you posted were the commands I have forgotten to add. Good job on your research. I will be looking forward for that beer ;-))
