I want to know how to install a Secondary OS of FREEBSD with and Existing OS (Windows 2000 PRO)   I have 5 HDD Drives so I can Put the FREEBSD os on another drive but How Can I do this successfully and to be able to chosse the OS when the Computer boots up Like the Windows 2000 Boot Up Window that lets u selcet ur OS that you want to boot in. I have doen Multiple OS's before.   I looked at the Requirements for FREEBSD and I have met the Requirements.   thnx
