Recently I learnt a bitter lesson on installing FreeBDS-6.2-amd64. If you are prepared running FreeBSD and Linux on the same box, on the 1st screen you have to partition the HD into 2 partitions, FreeBSD fs and ext2 fs respectively. On the 2nd screen you have to use the entire FreeBSD partition for cutting slices. Don't touch the Linux partition on FreeBSD. If you are going using the complete HD for FreeBSD only, on the 1st screen you have to use the entire HD as a single partition. Otherwise you can't find the HD on the 2nd screen.
