I also made a typo the first time I did it also. My g4l has nano editor, so it was just typing in the info. I'm planning on doing an full disk image, and then trying the grub2-install command and see if it runs ok, or has some message. Was hoping to get some feedback first, since it will take hours to do a full disk image of a 1TB disk. This is my 32 bit system for the my g4l build. Still need to upgrade my 64bit quad system to 16 as well...
