Did you actually choose the stick? I.e., did you press the spacebar to put an asterisk next to it?
You really need different hardware.
Yes..i used the new stick...if new ver11 stick is plugged in system where data hard disks are still connected to..i get message if i want to install freenas..i did choose yes there..so after ram warning message i get third message where i want to install on...hd1 or hd2 or stick...if u choose stick hrre i get message...you have to use at minimum one hard disk...but i am not sure if any of my own data will be overwritten then??? And i do not know which hd 1 or 2 i did use longer time ago for old version of freenas. Why am i asked..i thought freenas can be installed completly on a stick...
