Re: Dual Booting With Linux in Raid
my guess is that whatever drivers the installation kernel includes does not support the raid your motherboard supplies. Motherboard raid is in many cases a semi software raid depending on windows drivers for correct operation. Using it as an additional controller should not be a problem but the raid functionality might be.
I don't know what raid controller you have nor what the status of the linux support.
