this is becoming an FAQ for 8.0

the short answer is "dangerously dedicated" partitions are not supported
by the 8.0 installer. back up your data. zero the MBR & partition table
with dd, and re-slice & partition your disk. after the install, restore
from your backups.

search the freebsd-current archives for full details.
