The operating system needs to be installed with the BIOS already set to support RAID, otherwise the operating system installation will not have the proper drivers to boot up and it will loop on a system restart or a Blue Screen of Death (BSOD).
So, you should set the system to RAID, and try a fresh operating system installation from scratch and load the appropriate F6 driver for the installation, or have the correct driver for the slipstream media you are using.
I was able to perform a fresh install and the system is working properly. Of course now one of the drives in the RAID1 is complaining about SMART errors...When it rains it pours.
Hey jabouley, I am glad to know that you were able to get the system to work on RAID mode now.
Concerning the S.M.A.R.T. errors, I would recommend you to update the Intel(R) Rapid Storage Technology to the latest version
And check with the hard drive with the hard drive manufacturer. Probably you will need to do so on another computer since some S.M.A.R.T. values cannot be seen when using a RAID configuration. A full description of this is available on the following site:
