Not booting after adding mirrored drive

Windows Server 2003 with a single IDE drive.  I added a RAID conotroller and second identical drive.  Configured the Array and was careful to cable the primary channel to the boot drive.  After data synchronized the system won't boot.  Any ideas as to why?

Did you add a RAID driver to the system?  Systems with RAID controllers frequently need the RAID driver installed.  You also need to set the boot priority device in the BIOS to the RAID array.

just to be sure, the RAID array build from 2 IDE drives ?
did you check bios configuration ? (boot order etc)
do you get any windows boot screen ? (becouse if not ,i don't think it's driver)

great quick replies, thanks.  I removed the RAID controller and plugged the primary drive into the IDE on the MB and boots ok now.  So question revised:  How do I install a RAID controller and second identical drive to achieve fault tolerance without backup and reinstall of OS?

You dont need a raid controller, just need to connect the main drive to ide set as master second drive to same ide set jumper to slave and go to bios make sure it discovers it and boot up. goto disc management and r-click second drive and select mirror. your all done. Enjoy. Joel....

Try installing the RAID driver before you switch the hard drive to the RAID controller.  You will probably need to have the RAID controller present when doing this.

First go back to the original drive.
Install the RAID Controller while booted to OS
Shut down and connect drive to controller.
Boot system and see if it boots.
If not install windows to the second drive while connected to the RAID controller and look at the boot.ini file it creates.
copy this file to the original HD and you should be able to boot off of the controller and Mirror drives etc.

As has been said, you have to make sure the RAID controller works in Windows. If Windows can't see the controller, it can't see the drives on it. And, if it can't see the drives on it and Windows is on the drives on the controller, it won't be able to boot.

When I want to put Windows on a RAID drive like this, I always confirm the controller works within Windows first (as has been suggested already). The easiest way to do this is to plug a spare drive (or drives) into the controller. Once you see those drives in Windows, you're ready to go.
