I just tried for many a "happy" hour to clone a disk from an HP Pavilion Computer. An unusual feature of the disk is that the first partition is a recovery partition then Windows is installed on the second partition. The other complicating factor is that the disk I was cloning to was larger than the old one. I thought I could take the disk I wanted to clone out of the Pavilion and install it as a seconary drive in my computer running True Image (10). But that did not work. The cloned disk would not boot. I just got a flashing cursor on a black background and no attempt to start Windows. I tried making an image of the old disk and writing it to the new one. Didn't work. I tried again. Didn't work. I tried connecting both disks and cloning one directly to the other. Didn't work. Finally, I (temporarily) installed True Image to the Pavilion and cloned the disk. THAT WORKED. But then I had to go to the trouble of removing True Image from the cloned disk and the original one. Can anyone explain why I could only clone a disk when it was installed in the computer it "belonged" to?
