I've tried different RAID modes .
I have come to the step where different partitions where the OS is installed .
I direct the desired partition , and starts the process.
Within minutes , an error indicating that the computer must be restarted due to an error I get .
As fast so I do not have time to find out which indicates failure .
Therefore , I really wonder if this server is compatible with Windows Server 2012 R2.
Or should I update the firmware RAID controller INTEL ....
thank you very much for your support
