    Scenario: I deleted the active partition of Windows 7 by mistake, and now Windows can not boot. Nevertheless, I’m a little bit lucky since I have created a backup for the very active partition at the beginning of time. How can I restore active partition with the backup when Windows can not boot?

    Solution: try using the free partitioning tool MiniTool Partition Wizard bootable CD, which can boot computer without Windows OS to image active partition on one disk to unallocated space on any disk connected. Next, let’s see detailed steps to restore active partition with the backup.

    Note: MiniTool Partition Wizard Bootable CD is an .iso file, so users need to burn it to CD, DVD, or USB flash drive with burning software at first.

    How to Restore Active Partition with Backup by Using MiniTool Partition Wizard


    Firstly, connect the bootable flash drive with computer or put bootable CD/DVD to CD driver so as to boot computer. After that, we can see the following interface:



    Here, we can choose where to start computer. “Boot from Partition Wizard Boot Disc (Safe Mode)” is highly recommended.



    Then, choose a suitable display resolution and MiniTool Partition Wizard will start to get the following interface:



    The free partitioning tool shows all partitions and disks in this interface, but for sake of data security all partitions do not have drive letter, so please choose the backup of active partition according to partition features, such as capacity, file system, and partition type. Then, click the function “Copy Partition” from the left pane.



    Next, choose an unallocated space from the original system disk to create the copy of the selected partition, and then click “Next>” button. If there is no such unallocated space, users can shrink or delete a primary partition to release.



    Next, change the size and position of the newly created partition and click “Finish” to go back to the main interface:



    Now we can preview the new partition. Please set it primary if it is not, and then set it active.

    At last, click “Apply” button to apply all pending changes to computer.

    After these operations, we can shut down the free partitioning tool MiniTool Partition Wizard Bootable CD, and then Windows will boot successfully. In other words, we restore active partition via its backup successfully.
