Recovering a disk backup to a different disk under rescue media
Recovery of a disk backup containing several partitions to a hard disk that has a different capacity is one of the most complicated operations. This is especially true when the original hard disk you have backed up has a hidden diagnostic or recovery partition.
Complete the preparations described in Preparing for recovery.
If you have not already done so, assign unique names (labels) to the partitions of your computer’s disks. This will allow for identification of the partitions by their names and not by the disk letters. Disk letters may differ when booting from the rescue media. The names will help you find the drive containing your backups, as well as the target (new) drive.
Information on partition sizes, drive capacities, their manufacturers, and model numbers can also help to correctly identify the drives.
It is highly recommended to install the new hard drive to the same position in the computer and to use the same cable and connector that was used for the original drive. This is not always possible, e.g. the old drive may be an IDE and the new drive may be a SATA. In any case, install the new drive to where it will be used.
