You can tell the system to boot from an arbitrary disk and kernel file from the boot prompt. There's a man page at http://www.freebsd.org/cgi/man.cgi?query=boot&apropos=0&sektion=0&manpath=FreeBSD+4.6-stable&format=html But the invocation you want is something like: boot: 1:da(0,a)/kernels/kernel-new Once you've got your system running you can update the master boot record on da0 using fdisk(8) and/or boot0cfg(8) so that it will give you the option of booting up any of your OSes. Then you may need to reboot to get your loader config stuff back. Alternatively, you can boot up sysinstall from your installation media and reset the MBR through that program. Go into the 'Custom Installation' menu, then the 'Partition' menu. Hit 'q' to quit the partition editor without modifying any partitions, and the next screen will let you choose how the boot manager will be reinstalled when you go to the 'Commit' menu item.
