If you are using a seperate true hardware RAID card i dont think you would encounter the problem you face, it only happens when you are using the onboard RAID solutions which are only software no matter what they claim to be.
If you are not using windows at the moment, i suggest removing your RAID setup. (if you do have windows then i suggest creating two partitions of equal size of both hdds for windows, the rest as follows which is what i would do)
1. Leave your BIOS settings as RAID (this worked for me and some friends, you can try leaving it as normal)
(On the Remaining space if using windows)
2. Create 256MB partition each on both hdds (hdd space is plentiful nowadays and i am keeping the space left on both hdds equal)
3. Create a SoftwareRAID using the Install Disk on the remaining space, in fact you can choose RAID 0, 1
(or 5 -> not recommended on two hdds even though i am doing it
)
4. Use the 256MB on the first hdd to be /boot and the one on the second hdd to be your swap
5. Install your Boot Loader onto /boot partition instead of the MBR to keep all your OSes happy and less hassle for you if something goes wrong when you have a multi-boot setup
I hope my suggestion helps.
(with windows it would look like this : /hda1 -> /boot, /hda2 -> /windows/C, /hdb1 -> swap, /hdb2 -> /windows/D, the rest would be your RAID setup)
cheers!
