Ghost 14.0 will not create hard drive backup while windows is running

Hello,

 

This is my first post on the board. I am using Ghost 14.0 and am running Windows Vista. When I try to create a full hard drive backup, I get an error message. The message says that the backup cannot continue while windows is running. Then it says that the backup must be made in the "Recovery Environment". I am not sure what this means. Any suggestions?

 

Thank you
