It's another ISO image you burn to CD and boot.  It's a live filesystem off CD.

Since it doesn't depend on your hard drive's filesystem - it can boot
to BSD, and give you a emergency repair environment to do your work
(including mounting your HDD partitions) and then restart with the
hard drive.  Windows still hasn't got that down, yet.
