Im trying to start HA but i have the massage “Preparing Home Assistant” and it will take 20 minuts or so and it will not go to the welcome screen whats going on, i use a PI3 B with 32Gb SDcart.
It can take a long time. Be patient! 
After long time waiting I took a new SDcart and it works 
Thanx for the quick responce Im new at Home assistant and im coming from Node Red and Blynk
