Good Evening!
I ask with courtesy and, in practice, as you start the dvd Norton Bootable Recovery Tool:
Step 1: I put the DVD into the drawer of my computer
Step 2:
1) The Press Start and then start again.
2) When the system asks me to press any key to boot I have to press F2?
3) One or more times I have to press F2?
The specification that I ask you as to the point 2 and point three.
Thanks to those who respond
