I had my old MediaSmart server recently upgraded (headless) to WHS 2011 with a cfg.ini, now I f*cked something up and the whole OS is broken. This is the perfect opportunity to upgrade again (I love to install things hahahah) to WS2012 R2 Essentials, yet as a beginner this whole unattended.xml goes way over my head compared to a simple cfg.ini, I tried some but it didn't work. Anyone ever succeed to do this headless and/or got a good setup file? Or any tips?
