I have read and re-read the instructions and forum posts, but not sure I entirely understand the language Acronis uses. Is there a difference between cloning and imaging? At any rate, this is what I have done. I have moved the few important files I have--mainly pictures, favorites, and email addresses to a DVD. I purchased and installed a 2nd HD for my Dell XPS 410 which is identical to the original drive. I got help to create a dual boot. My original intent was to place Windows Vista on the 2nd drive, but I learned there would be too many incompatibilities. So I cloned the original C drive to the new D drive using Acronis TIv11. (I booted to each individually as a trial and both drives worked fine.) Then I established the new "D" drive as the boot drive in the bios. Now I was getting in over my head............. My new intention was to monthly, manually create a clone of the boot drive, now "D" to the other drive "C", and go on like that indefinitely. I know this is not the way most people perform backups, but my info does not change often. Now the questions. Since "D" is my boot drive, how do I change Acronis to do D to C drive? The problem I see of doing this is that I have to change the boot order in the bios each time, and at some point this will get onerous. Am I just spinning my wheels? Do you see any other problems ahead? To my embarassment, I have no idea how to get back from dual boot to normal boot and just go back to having 2 completely separate drives and do the normal backup process. I assume I will have to work in the Bios, but this is getting too complicated for this 70 y/0 brain. The help I got for setting up dual boot is no longer available. Any suggestions? My computer will no longer boot automatically with one drive removed. And I have not seen anyone post here or elsewhere who use dual boot for cloning and B/U.
