RAID 1 interfering with linux installation

[Rick]

I've got an E520 Dual Core, with two 320 GB SATA drives connected 
through the Intel RAID 1 controller.  When I had the opportunity 
(read: necessity) of reformatting the drives and reloading Windows, I 
partitioned them into three sets of 100 GB each, putting Windows on 
the first partition, an NTFS format on the second one, and leaving 
the third as unformatted space.

So far, I've tried Ubuntu v6.10, Solaris 10, and Redhat Fedora Core 6 
on that remaining space.  All install smoothly, until you reboot and 
never see the Grub installer, with Windows coming up 
directly.  Finally with the Fedora, I checked the advanced options 
for the grub install and told it to install on the RAID partition 
instead of the c: drive.  That caused a "grub hard drive" error on 
the next boot, only fixed by booting the resource DVD and running one 
of the fix utilities.

How can I get a flavor of linux installed in a dual boot 
configuration?  That RAID controller seems to be the issue here.
