Redhat can as well using either Lilo or Grub. Personally I have not managed to make Grub boot into a FAT32 system but I only tried once, weakly at that. I do have a couple of dual boot Rh7.3/Win2k sytems that use NTFS and had no problem getting Grub to work right. Ont he one that didn't work one of the drives was IDE, the other SCSI. That might have been my problem. Dunno. Didn't really spend any time thinking about it until now.
Install the Windows O/S first, then RedHat. I find it a lot easier that way. Usually lilo figures it out on it's own. I had to tinker with the grub.conf a lil. One small change and it was working fine.
