password at boot

What do you mean by prompt Password? What do you expect? 

The XG ask the admin password on the screen at the startup .

Try admin/admin, or the password you defined in the wizard. Backups do not contain passwords of admin. 

I know the password, but i don't want XG to ask me at every boot ...

I dont understand. What do you mean by every boot? The OS is loaded and works fine. The prompt on CLI / console is standard. 

Probably means you haven't registered your XG licence.

That was a guess while I thought through the issue.

What you are seeing is what the XG does every time it is started/restarted when you leave the console connected. The console displays this so you can access the XG using CLI type functions.

If you don't want to see the password prompt don't connect the console, you don't need the console to restart the machine you can do that function from the GUI.

ther is also the possibility that you have auto line feed/cr enabled on you console connecting device.
