How did you do those two installs though? David is not saying that
dual-booting does not work. He is saying that the sysinstall step
can get in your way, depending on how you try to create the two
systems you want to boot between. Once you GET the slices and
partitions set up right, then the booting process can easily handle
multiple freebsd systems on a single disk.
For instance, in the following sequence you should not run into
any trouble with sysinstall:
first set up a dual-boot system with the first dos-style
slice being Windows, and the second one holding freebsd.
after running this way for awhile, you decide that you do
not need windows any more. So you again boot off the
FreeBSD cd, you blow away Windows, and you install a second
snapshot of freebsd on the slice which used to be Windows.
For both of those freebsd installs, at the time of the install the
first slice on the disk which was of type freebsd was also the slice
that you wanted root (the '/' partition) of the new installation to
be on. So, sysinstall has no trouble with what you want to do.
Where you have trouble is if you have two dos-style slices defined,
both of type freebsd, and you want sysinstall to install into the
second of those two slices.
