Assuming that you see the instruction on your screen to hit the F10 button for system recovery, hit the button about once a second while the computer boots - continue pressing the button. This should get you into the system recovery area. Usually the first option for recovery is the non destructive type, go into 'advanced' options in order to do a destructive type of recovery.
The recovery console that you booted to using the disk is NOT what you want. That is simply a tool that can be used to make a few repairs to Windows, if you know the commands.
If my advice does not work, please tell us what make and model computer you are asking about. That would help a great deal.
