DSS v7 on Dell R720

I didn't try USB, but tried to boot the system from CD, the same. I will try USB, but does it make any difference?

It does not make a difference using a CDROM or USB to boot to test but the USB is faster and you can write to the USB as CD you cant. We did certify the Dell 720 so this is strange how you not able to get this to install, you could install the DSS on the boot media and use the config.exe file in the DSS to remove the installer. But lets get you to where you can boot.
