The program warns you that all data on the target disk will be overwritten in the process. You may also select cancel to postpone it. Just select 'ok' on the screen to start the cloning right away. Macrium Reflect Free displays a 'what do you want to do now' prompt next. Select the finish button to complete the configuration. There you find information about the cloning and each of the partitions that the backup app will copy in the process to the new drive. Macrium Reflect Free displays an overview on the final screen. Since this is a one-time operation, there is no need to schedule the task so that it can be executed again in the future. Select next to proceed and then next again to skip the scheduling part. The two disks do not need the same amount of space, but there needs to be enough free space available. Note that you need sufficient space on the new disk so that all data that is on the source disk can be copied. You should see an exact copy of the disk structure after the selection.

Once done, select the copy partitions button and then 'exact partition offset and length' from the selection menu.

Since you want to copy the system disk, you need to make sure that the entire disk is free.

Use the 'delete partition' action to remove any existing partition from the second disk.
