Accidentally deleted recovery partition - MiniTool Solutions

Have you ever accidentally deleted your recovery partition? However, do you know what recovery partition is? What should you do after deleting recovery partition by mistake? Is it possible to recover accidentally deleted recovery partition? Now, this post will show you all answers in order.

Recovery or restore partitions are dedicated memory sections on your hard drive that you can use to restore your machine to factory settings. So, if your computer keeps freezing or crashing, you can access the recovery partition to recover your system.

But if you accidentally deleted the recovery partition, you don’t be able to do that. You need to first recover the deleted partition.

In this article, I’ll show you exactly how you can do that.

Recovery Partition

Recovery partition, sometimes we called it restore partition, is a special section set aside on 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.

Step-by-step guide on how to restore a deleted recovery partition

Launch MiniTool Partition Wizard. Then, you can see all partitions as well as some information (like capacity, file system, type, and status and more) and some basic features are listed in this window.

Now, select or right click the disk which is suffering partition loss and choose "Partition Recovery" from the left panel or from the shortcut menu. 


After that, set scanning range for the selected disk. ("Full Disk" is suggested when you do not know where the lost partition was located.

"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. 


After scanning, all existing partitions and lost partitions are shown. In this window, check all needed partitions, including lost/deleted partitions and existing partitions.

And then click "Finish" button to go back to the main interface: Note: unchecked partitions will be lost even if they exist now


Now you can see the deleted recovery partition, but it does not have a drive letter. To make it visible in "Computer", you need to appoint it with a drive letter.

Finally, click "Apply" on the top and tap "Yes" to perform all changes. 

After all operations are done, you have successfully recovered deleted recovery partition from your PC. In a word, Partition Recovery feature is a quite good solution to partition loss.

At the same time, it can recover lost data as long as new partition hasn’t been created. If this software is right for you, you can download and give it a try. 

Solution 2: Create A New Recovery Partition

Note: here I 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. 

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

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 i…aged or formatted post will tell you more details. 

Generally, 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. 

You can select a suitable method that best suits your demands.
