How to Recover Deleted or Lost Partition on Windows

Losing a partition on your Windows system can feel like a nightmare for any user. Whether due to a faulty operation, malware, or simple human error, a lost partition often contains important data that seems irretrievable. However, there are several methods to recover a deleted partition on Windows. In my personal experience, patience and the right tools can turn what looks like a disaster into a recoverable situation. This article will guide you through various methods that I’ve used to successfully restore deleted partitions and safeguard crucial data.


Common Scenarios:

Accidental Deletion 🗑

  • Human Error: Perhaps the most common cause; accidentally formatting or deleting the partition while tinkering with disk management.
  • Software Conflict: Sometimes, installing or uninstalling software can inadvertently affect the partition table.

Partition Table Corruption 💥

  • Malware or Virus: A malicious software infecting the system can lead to partition table corruption.
  • Power Outage: Sudden power loss while disk operations are in progress might corrupt the partition information.

Disk Management Mishaps 🛠

  • Disk Management Errors: Incorrectly using the built-in Windows Disk Management tool can result in lost partitions.
  • Third-party Tools: Improper use of third-party partition management software can sometimes delete partitions.


Step-by-Step Guide. Recover Deleted Partition:

Method 1: Use Windows Disk Management 🧰

  • Open Disk Management by pressing Win + R, typing diskmgmt.msc, and hitting Enter.
  • Look for unallocated space where your partition used to be.
  • Right-click on the unallocated space and select New Simple Volume…
  • Follow the wizard to recreate the partition. Make sure not to format it if you hope to recover data later.

Note: This method will not recover your data but can prepare your disk for data recovery software to do its job.

Conclusion: Though simple, this approach is useful when dealing with non-formatted deleted partitions.

Method 2: Run the CHKDSK Utility 🛠

  • Open Command Prompt as an administrator.
  • Type chkdsk /f X: where X is the letter of the missing partition and press Enter.
  • Wait for the process to complete. This may take some time depending on the size of the disk.

Note: This method attempts to fix file system errors which might make the partition visible again.

Conclusion: The CHKDSK utility is a powerful tool for repairing file system issues that could be preventing partition access.

Method 3: Restore from System Restore Point 🔄

  • Navigate to Control Panel > System > System Protection.
  • Click on System Restore… and follow the prompts to select a restore point prior to the partition loss.
  • Complete the system restore process.

Note: Make sure system protection is enabled and you have created restore points.

Conclusion: This method can potentially bring back your partition configuration to a previous state.

Method 4: Use a Partition Recovery Tool 🧲

  • Download and install a reliable partition recovery tool.
  • Open the tool and select the disk where the partition was deleted.
  • Follow the software instructions to scan for and restore the deleted partition.

Note: Such software can often recover partitions with the data intact.

Conclusion: Using a partition recovery tool is one of the most effective ways to recover a lost partition and its data.

Method 5: Rebuild Master Boot Record (MBR) ⚙

  • Boot from a Windows installation media.
  • On the setup screen, click ‘Repair your computer’.
  • Choose Troubleshoot > Advanced options > Command Prompt.
  • In the Command Prompt, type bootrec /fixmbr and then bootrec /fixboot.
  • Reboot your system to see if the partition appears.

Note: This method is useful when a corrupt MBR is the cause of the missing partition.

Conclusion: Rebuilding the MBR can restore access to partitions if the problem lies with the boot process.

Precautions and Tips:

Protect Your Data 🛡

  • Regularly creating backups of your data is crucial to avoid losing important files.
  • Enable System Restore in Windows to create restore points before making significant changes to your system.
  • Always double-check before performing operations on disk partitions.

Preparation is Key 🔑

  • Create a Windows recovery drive for emergencies.
  • Keep a reliable third-party partition recovery tool installed on your system.
  • Be cautious when installing new software that could impact disk partitions.


Further Insights

When it comes to data recovery, time is of the essence. The longer you wait after a partition is deleted, the higher the chance that new data will overwrite the lost data, making recovery much more difficult. If you notice that a partition is missing, stop using the disk immediately to avoid overwriting the deleted data.

Data recovery services are also an option if you’re not comfortable performing these steps yourself, or if the data is particularly valuable. Professional services like DriveSavers can often recover partitions and data that software cannot.

Also, consider the Windows File Recovery tool, a command-line utility from Microsoft that can help recover files. While it doesn’t specifically recover partitions, it can be useful for retrieving files after you have re-established the partition.

Remember, while DIY solutions work in many scenarios, they are not foolproof. Valuable or sensitive data may be best entrusted to professionals.


In conclusion, recovering a deleted partition on Windows is definitely possible and something I’ve managed on multiple occasions. It requires a level of technical knowledge and sometimes a bit of luck, but with the right tools and techniques, such as Disk Management, CHKDSK, system restore, partition recovery software, and rebuilding MBR, the odds are in your favor. Just remember to take precautions, like regular backups and the creation of a recovery drive, to protect against data loss in the future. Above all, don’t panic – help is usually just a few clicks away.


Yes, it's often possible to recover a deleted partition using specialized software that scans the drive for lost data signatures.

Before attempting recovery, stop using the affected drive to avoid overwriting data and back up existing partitions if possible.

Yes, many recovery tools are capable of restoring the original file structure, but success can vary depending on the extent of the data loss.

There are free tools such as TestDisk, which can be used to recover partitions without cost.

Most recovery software supports common file systems like NTFS, FAT32, exFAT, HFS+, and EXT3/4.

SSD partitions can be recovered, but it's more complex due to the way SSDs handle data deletion with TRIM.

Professional help is not always necessary, but it can be beneficial for complex or severe data loss scenarios.

The recovery time can range from minutes to hours, depending on the size of the partition and speed of the recovery tool.

Recovery can be more challenging after a reformat, but it's still possible if new data hasn't overwritten the old.

One reliable option is Disk Drill, known for its user-friendly interface and effectiveness.
