Acrnois Startup Manager Password?

Hello.

I asked a question 1 year ago about password protected Acronis Startup Manager. http://forum.acronis.com/forum/8715

I have created Acronis Security Zone and Activated Startup Recovery Manager and I can acess it by pressing F11 when my computer starts. OK

There are kids at my home who use the same computer, they often press F11 and play arrount Active Recovery Manager. I am curious because they can also acess Acronis Disk Management Utility and Delete Partitions without any limitations.

Can you tell me a way to get rid of this problem.
