Hi,  I got a Dell R520 with the following specs 2x processors 32 GB Memory 8x 2 GB NL SAS (RAID 5) PERC H710 ------------- I set up RAID 5 with all 8x Disks then I restarted the servers and loaded the Windows 2008 R2 DVD installer.   Tried installing Windows 2008 R2 STD. I could not find any hard disk / virtual disks to install the OS ?   Hope someone can point me to the right direction.   Thanks, Paul
