Ye olde sysinstall did - you could just leave the MBR
untouched. If this is a problem in bsdinstall, here's
a simple way around it: Allocate the disk space per
command line (gpart, newfs), then return to the installer
menu and use the (now) "existing file systems" as target.
There should be nothing left that messes wuth the MBR.

That should be easy to prepare with gpart and gmorror.
Warren Block wrote an article about that topic which
you'll find helpful:
As far as I understand, this applies to the FreeBSD
part of the installation. Linux should support GPT
and will need different but similar configuration. :-)

A good decision. :-)
