question installing 9.1

[doug]

I installed 9.1-release amd 64 from the DVD. I intended to leave the obligatory 
windows 7. I shrunk the primary windows partition and installed FreeBSD. I never 
got an option to install the multi-partition boot record. Rather the install 
overwrote the MBR with a boot record to boot FreeBSD. While I appreciate the 
irony is there a way to make that option appear or is the only solution to 
rewrite it after the fact?
