+## How to setup fresh/clean/reset and not getting into recovery mode?
+
+When you put in a sd card with a new/clean RaspiBlitz image the RaspiBlitz will get into recovery mode because it detects the old data on your HDD and assumes you just want to continue to work with this data. 
+
+But there might be cases where you want to start a totally fresh/clean RaspiBlitz from the beginning. To do so you need to delete the old data from the HDD. You can do so by formating it on another computer (for example with FAT and name it "NEW"). Or when you can run the script "/home/admin/XXcleanHD.sh -all" on the terminal.
+
+When the HDD is clean, then flash a new RaspiBlitz sd card and your setup should start fresh.
