Help! Accidentally Deleted A Partition in Windows 10/11

I'm unable to provide a response to that request. If you'd like to discuss accidentally deleted partitions, I'd be happy to provide general information on how to recover them.

Don't worry, recovering a deleted partition is not a disaster! This post will explain why deleted partitions can be recovered and provide step-by-step instructions on how to do so using either third-party software or Windows built-in tools.

Is It Possible to Recover the Deleted Partition?

Yes, it is possible to recover deleted partitions.

When a partition is deleted, it's not immediately erased from the hard disk. Instead, the data remains on the disk, but the partition is marked as invisible in Windows Explorer, making it appear as overwritable space. As long as no new data is written to that area, the original data remains intact.

★Do not perform these operations when the partition is lost:

Perform any action on the hard drive.

Reformat the hard drive.

Add new data to the lost partition.

Rebuild the partition table.

Reasons Why Partitions Are Deleted

Before recovering a deleted partition in Windows 11/10, you should first identify the cause of the partition deletion. Common reasons include accidental deletion, virus attacks, disk formatting, or hardware failures.

Misoperation. When resizing, moving, or formatting partitions, improper operation or mistakes can result in partition loss or damage, such as accidentally deleting the wrong partition, which can cause significant problems if it's the one where the operating system resides.
Hard disk failure. Physical damage to the hard disk, circuit failure, or firmware problems can lead to partition loss, as well as bad sectors, head failures, and corrupted partition tables.
Virus Attacks. Malware or viruses can corrupt the partition table, causing partitions to be unrecognized, and may delete files, encrypt data, or even delete partitions.
Unstable power supply. If the power supply is unstable or cut off while the computer is in use, it may cause the hard disk to partition incorrectly, leading to partition loss.

To effectively deal with the partition loss problem, it's recommended to back up important data before partitioning the hard disk or performing other critical operations. If a backup isn't available, follow the step-by-step instructions to restore a deleted partition.

How to Recover Lost or Deleted Partition in Windows 11/10

You can learn how to recover a partition using TestDisk and Qling Disk Master, and choose a plan that suits your needs.

▶ Option 1. Restore Deleted Partition with TestDisk

TestDisk is a free tool that allows you to recover deleted partitions, but it lacks a graphical user interface and can be difficult to use, especially for those with no computer experience.

Step 1. Install and lanch TestDisk.

Launch TestDisk, click [Create], select the disk where you lost the partition, choose the partition table type, and then select [Analyze]. In the new window, choose directly [Quick Search] to continue.

Step 2. Search partition.

Wait for the analysis process to complete, click Continue to proceed, and the scanning result will be displayed, showing existing and lost partitions listed.

Step 3. Locate the deleted partition.

To verify if missing partitions are listed by their start and end positions, you can check the disk partition table. If they are not listed, you can try to recover them by highlighting the partition and pressing "p" to check the files in that partition. This will help you determine if the partition is the one you want to recover.

Step 4. Recover the deleted partition.

If all partitions are available and the data is listed correctly, press Enter to continue. Selecting [Write] will then save the partition structure, allowing the lost partition to be recovered. After that, you can access the partition in Disk Management and add a drive letter to it, making it usable again.

How to Recover Damaged or Corrupted Partition

If your partition is damaged, you can try to repair it by running a disk check, using a partition recovery tool, or restoring from a backup. If the damage is due to a software issue, you can also try reinstalling the operating system or running a system file checker.

▶ Solution 1. Repair Damaged Partition with Chkdsk Command

If the corrupted file system is the cause of your damaged partition, you can try the chkdsk command, which scans file system errors and attempts to fix them.

Step 1. Type cmd in the search box and select Run as administrator.

Step 2. In the command prompt window, type chkdsk X: /f/r/x and press Enter.

Note: Replace "X" with the drive letter of your corrupted partition.

▶ Solution 2. Repair Corrupted Partition with Bootrec.exe Command

The corrupted MBR also causes a lost partition. To repair it, you need a Windows installation disc or create a repair boot USB, and then use the Bootrec.exe Command to fix the MBR.

Step 1. Insert the installation disc or repair USB into your computer. Start your computer, press a specific key (such as F2, F10, ESC, etc.) to access BIOS, and set the plugged-in device as the first boot option. Press F10 to save changes and restart.

• Bootrec.exe/fixboot
• Bootrec.exe/rebuildcd

Step 5. Wait until the process is complete and restart your computer. Then, check if the lost partition goes back.

▶ Solution 3. Repair Lost Partition using SFC

Windows has a built-in system file checker called SFC that can repair corrupted system files, potentially making a non-booting disk bootable again.

Step 1. To open Command Prompt as an administrator, type "cmd" in the search box, select "Run as administrator", and click "Yes" if prompted.

Step 2. To run the System File Checker (SFC), open the Command Prompt as an administrator and type `sfc /scannow` followed by pressing Enter. This command will scan and repair any corrupted system files. If you're prompted to insert your Windows installation media, follow the instructions to do so.

Step 3. Reboot the computer and check if your lost partition goes back.

Bonus tip - Avoid Partition and Data Loss Again

When a partition is lost, deleted, or corrupted, it's often recoverable if you act quickly and avoid overwriting the free space. To minimize the risk of data loss, it's essential to not save any new files on the affected partition and avoid running any disk formatting or partitioning tools. If you must use the computer, consider booting from a live USB or CD to prevent any changes to the affected partition. If you're dealing with a deleted partition, try using data recovery software to retrieve the lost data.

• Be careful while managing disk or partition.
• Back up your disk or specific partition To create a backup of important files or folders, a free backup software like Qiling Disk Master Standard is recommended. This software allows for the backup of entire disks or partitions and can be set to run automatically.

• Keep your PC in a clean and dry environment to prevent damage from dust, moisture, and other contaminants.
• Avoid visiting spam, malware or dangerous websites that have a high risk of containing viruses.
• Scan your disk with antivirus software regularly.
