I've been trying to use the copy drive setup in Ghost 15 on my Windows 7 computer to upgrade to a larger drive, but after several times of trying & instaling the lager drive in the computer, it says there is no MBR. I an sellecting Set drive active & Copy MBR, but still nothing. I am attaching the new drive via a USB port, which I understand is supposed to work. Can someone advise? Thanks for your help in advance.
