Well, it's either Win2K or Windows 7 then... Your choice I'm going to get RAID drivers for Windows 2000 and see if I can get it from choking up. It isn't a choice of "pick one", it's just a slight nuisance that I have to enter BIOS every time I want to load 2000. I fixed the bootloader, and in either RAID or IDE Windows 7 bootloader will take me to 2k or 7. So, not too huge of an issue, just a nuisance.
