Others have given good basic advice. One more bit of advice: If you're
using an older system, create separate /boot partitions for each
distribution below the 1024-cylinder mark (about 8GB on most computers,
but 504MB of *REALLY* old systems, like from before the mid-1990s). Some
people have had luck using a single /boot partition for both
distributions, but my experience is that this often causes weird
problems, so I wouldn't recommend it. The reason for this is that older
systems didn't support booting from beyond the 1024-cylinder mark, so the
kernel had to be kept below that point. Putting the kernel on a /boot
partition below the 1024-cylinder mark makes it easy to accomplish this
goal.

FWIW, I wrote a book on multi-booting -- see
http://www.rodsbooks.com/multiboot/ for details. It's getting a bit long
in the tooth now, but might still be worth picking up if you can find a
copy at a good price.
