Thank you for that!
I used an exteranl DVD drive and it let me go further as I was able to install the drivers and see the HDD's, but wasn't able to install Windows 7 (See screenshot). I've tried deleting the the partitions, recreating them,formatting them etc... with no success.
One thing I did notice was that when I created a RAID array volume , Windoes setup was unable to see the volume. I dont't need a RAID volume for this particular machine and can get by with a single disk and a copy of WIN 7.
