Thanks Scracy, that seems to be the issue. I figured it was something simple. I don't know how I missed it and worse, why the board defaults to this option...
So if I toggle that option back to IRST, I *may* have to reinstall? It says in the BIOS that I will need to reinstall. This sucks because I have a complex installation.
Windows is installed to a 240GB SSD, the user and programd data folders are set to install to a 2TB RAID0 array consisting of 2x 1TB drives. Additionally I have 2x 2TB drives in there for additional storage. Since Windows itself should not be affected by the change over, might I only have to perhaps backup the two other folders on my 2TB array and load them back on? Also, will the arrays simply be lost after the switch over?
Thanks
