    Overview of Recovery Partition


    Recovery partition, sometimes we called it restore partition, is a special section set aside on OEM computer hard drives. Manufacturer's like Acer, ASUS, Dell, eMachine, HP (Compaq), and IBM computers use this section of memory to hold the information used to restore your computer back to its factory settings. This feature is especially useful because it does not require the operating system's CD or DVD. And, recovery partitions carry advantages over disc-based solutions, including a faster recovery process (as the data is directly on the hard drive and no disc swapping is needed), and less cost to the OEM as they do not need to ship recovery media with the computer.

    Recovery partitions are typically accessed either through a pre-installed Windows application or by pressing a specific key combination as the computer boots up. If your computer crashes, you can startup recovery software and activate recovery partition to recover your system. This process is just like reinstalling system.

    There are some points to inform you:
    Nearly all recovery partitions with computer brand only can be installed in their branded computer. For instance: Lenovo Onekey Recovery can only be installed in Lenovo computer. All system images can’t be distinguished by other recovery software.


    However, recovery partition loss is a common thing. For instance, you delete restore partition by mistake; or your hard drive fails; or your hard drive is fully formatted; etc.

"Unallocated Space" is recommended if you haven’t created any new partition after partition loss. "Specified Range" scans specified sectors.) Here, you can choose "Full Disk" and then click "Next" to continue.

    Third, set scanning method for the specified scanning range and then click "Next" button.

    Solution 2: Create A New Recovery Partition


    Note: here we take Windows 8 for example.
    Step 1: Download your Windows ISO directly from Microsoft, which will require your product key to install. (Note: In many cases, this is included with your Windows computer.)
    Step 2: Use Microsoft’s tool to create installation media for Windows.
    Step 3: Look for the Sources folder, where you’ll find install.esd. This is the recovery partition, basically, but in its current state it is useless. To make it work for you, you have to first move it from the ISO or DVD to a location on your hard disk. Next, you need to convert it from install.esd to install.wim via some converters like WimConverter tool, and then copy the install.wim file to a new folder on your C:\ drive, labeled C:\Win81-Recovery. The next stage is to register the file so that Windows knows it is there and can create a recovery drive.
    Step 4: Right-click the Windows Start screen button and select Command Prompt (Admin) on the desktop. Next, in the command line, enter:
    REAGENTC /SetOSImage /Path C:\Win81-Recovery\INSTALL.WIM /Index 1
    Tip: This will register the INSTALL.WIM file as your PC’s recovery image.

    REAGENTC SetOSImage Path CWin81-RecoveryNSTALLWIM ndex 1

    Step 5: Type: REAGENTC /Info.
    Step 6: Type: exit.

    In a word, creating a new recovery partition is indeed an effective solution, but it requires complicated operating steps and skills. Now, let’s continue to say some simple solutions.

    Solution 3: Turn to The Preinstalled Recovery Software in Computer


    As we know, some branded computers have configured their own recovery software. Such as Lenovo One key Recovery. It doesn’t require users to prepare any external storage devices except installing Lenovo One key Recovery. Therefore, if you accidentally deleted recovery partition Lenovo, you might try using this software. Here, this How to recover preloaded Windows if hidden partition was damaged or formatted post will tell you more details.

    In a word, although this solution can help to restore the system partition to its original status, it does not apply in all cases. Besides, Lenovo One key Recovery only works with Lenovo computer, so it cannot help you if you accidentally deleted recovery partition ASUS/HP.

    Sum up: after seeing the above 3 solutions, you can select a suitable one to get your recovery partition back.

    Necessary Tip for Managing Recovery Partition


    As we know, computer manufacturers now provide a recovery partition (a hidden portion of your hard disk where a copy of the original system configuration is stored), which can help to restore the PC to its original factory state.
    However, sometimes, you may find recovery partition is occupying too much space. At this time, you may want to delete recovery partition to get more free space.

    Now, you might be wondering:

    "Is it possible to delete recovery partition to free up more disk space?"


    In fact, as long as you have a copy of Windows installation or recovery disk or recovery drive, you can safely delete the recovery partition. Next, we will show how to make a full backup of a Windows PC, and How to Create and Use a Recovery Drive or System Repair Disc.

    Steps on making a backup of Windows


    In general, MiniTool Partition Wizard an excellent feature – Copy Disk to help backup the whole disk in case of accidents.



    SEE!
    Launch MiniTool Partition Wizard, select or right-click the disk which needs copying, and then activate "Copy Disk" feature from the left pane, or choose "Copy" button from the shortcut menu.

    copy disk

    Afterwards, select the disk that will save the copy of the source disk as the target disk and then click "Next" button. Note: the target disk should be large enough to hold all content on source disk, and you also need to backup all important data on this target disk in advance, because all its data will be deleted. If you didn't have a large hard disk, you can only Clone Windows Recovery Partition to External HDD.

    Next, choose a suitable copying method (Fit partitions to entire disk, Copy partitions without resize, and Edit partitions on this disk) to decide the layout of target disk and then click "Next" button.

    Tip:
    Please keep checking the option "Force to align partitions to 1MB" since it could improve performance of Advanced Format disk & SSD.
    If the target disk is larger than 2TB, we suggest checking "Use GUID Partition Table for the target disk", because it supports disks larger than 2TB while MBR supports the maximum disk size of 2TB.


    After that, click "Finish" button to go back to the main interface.

    Finally, click "Apply" button on the top left corner to apply all pending operations. Note: here you will be asked to restart your computer since you are copying system disk. Please just do as told.

(Here, MiniTool Partition Wizard also offers Delete Partition feature to help you remove a specified partition off.)
