RedHat Install equals MegaRAID confusion

I’m installing RedHat 7.2 on a server that has MegaRAID SCSI RAID controllers. The redhat install is seeing the first RAID drive as the first bootable device instead of the real first bootable hard drive. Win2K locates the C:\drive and installs fine. What Win2K sees as the F:\drive Linux is seeing as the C:\drive. As a result, Linux will not boot because it is looking at the wrong device as the first bootable drive. Help!
