Ubuntu doesn't see my RAID 1 Array after install

I have a computer that I've built that I'd like to load Ubuntu 9.10 on.  The computer has two WD 1TB SATA drives, Intel DG965WH motherboard and a 1.8GHZ Core 2 Duo CPU.  I'm using the onboard "Ctrl I" controller to configure the RAID.  I've configured the drives as a RAID 1 array.  I've loaded Ubuntu from the cd and it completes the installation with no problems.  The problem is once the computer restarts I get a message stating no bootable device.

I'm a newbee at Ubuntu so if there is something fancy I'll have to do I'll need simple instructions.  Thanks in advance.

It's not supported by Ubuntu.

Typically, onboard raid controllers like yours are only supported under windows as they need software drivers to enable the raid functionality.

If you want RAID - buy a proper raid card.
Go to the Intel website. There are LINUX drivers with source code for just about all of their controllers.  BUT it is a painful process to get it integrated as a boot device, and you will have to read the release notes, and effectively have to build a special LINUX distribution on your hardware with the RAID turned off.

Or ... LINUX's software RAID1 is well known, safe, and pretty easy to use. It is also going to be much faster than the embedded RAID1.  I recommend doing that instead.  Disable the RAID controller, and just read up on installing LINUX using the md driver and software RAID1.  Lots of  online articles.

Plus, software RAID on linux is the basis for a great number of NAS and SAN appliances that you buy commercially, due to the performance and stability.  You will be much better off going with software RAID.

It seems that your onboard "software"(they call it hardware assisted but actually software) RAID  was not fully supported by your UBUNTU kernel.

I'll suggest you to reboot and go to BIOS setup and change the drivers back into AHCI mode(native SATA). Then you can setup software RAID over your UBUNTU server.
