Select the necessary partition and click Next. 5. 3 Selecting a location to restore to As a rule, you should restore an image to the same partition from which it was created. You can restore an image to another partition, but this is not often necessary. However, a partition should be of at least the same size as uncompressed image data. If you don't have a special reason to restore an image to another partition, restore it only to the partition that was used to create the image. 22 Copyright © Acronis, Inc. , 2000-2005 Restoring disks (partitions) from images under X Window System Select partition to which the image will be restored All the data stored on the restored partition will be replaced by the image data, so be careful and do not overwrite data that you might need but haven't backed up yet. 5. 4 Selecting partition type When restoring a partition, you can change its type, though it is not required in most cases.
