installing Fc4_64 on hda2 and having Windows on hda1 grub on first boot comes to minimal bash like command line without the expected options (fedora, other). Please since this is the rc3 and there will be no other rc until the final version on june 6 take the time to test this bug!!! also seems that grub is not installing on MBR even when booting on rescue mode and try to grub-install /dev/hda
