It's very easy to create a GRUB boot floppy or CD. Just read the Installation 
section at: http://www.gnu.org/software/grub/manual/html_node/index.html

At a minimum you are likely to need to update GRUB whenever you upgrade or 
install a new kernel, repartition, or add/change drives.

Also, in an emergency there is a 64-bit version of Knoppix at 
http://www.applia.fr/contents/knoppix64.html that might come in handy.
