Thats what happens if i just flip the switch. i dont want to reinstall Windows if i can avoid it. Whats the correct, safe procedure to switch, and do i need to uninstall the RAID driver first? i have a backup of my documents, but Id really prefer to keep my installed programs and settings intact if possible.
