I created an image of my system with macrium reflect freeware program and stored the image on an usb external hard drive. However the macrium reflect linux recovery disc on startup hangs up of the first three lines of instructions and therefore I cannot access the image on the usb external hard drive if I wish to recover my system. I have a Lenovo laptop with the Windows-7 Home Premium operating system. What can be done to ensure that the recovery disc will work?
