While not uncommon, sometimes, you remove one that you didn't want to remove when managing Partitions. If this is the case, you are not alone. Windows offers a built-in tool - Disk Management - which allows you to manage everything when partitioning. However, when inexperienced users try it, it results in total data loss.

The post will help you not only bring back the lost partition but also recover data from it. So, if you are wondering how to undelete Windows 11 partition, you should follow our guide.

Causes of Partition Lost

Apart from accidental deletion of partition, some others reasons cause partition loss. The list includes

Hard drive corruption. Virus attacks. Malware activities. Improper system shutdown. Power surge. Improper format. Partition table damage. . There are more reasons, such as an accidental drop of laptops, power failure, hard disk damage, etc., which results in Windows 11 Partition deletion.

You need to be sure to have a backup of all important data before this unfortunate event occurs, but not everyone does that. This guide offers ways to get back the partition and also set up a backup system in place. This way, you will be able to recover the deleted partition even if you have lost all the data. You can even recover the data from the deleted drive.

It is important to know that it is not completely removed when a portion is deleted until a new one is created. It is only removed from the access of a general user and the OS. The information of such deleted partition is available on the hard disk. It can be recovered using some partition recovery software such as EaseUS Partition Master.

It's a professional application that offers more than simple disk management. The software is easy to use, offers an interface that makes sure there are no accidental deletions, and helps you recover lost partitions. Here is the list of features the tool offers:

  • Adjust the size of a partition to a larger or smaller one using the slider.

Bonus Tip - How to Protect Your Partitions

Like we shared at the start, it is important to have a backup plan in the first place before such a disaster happens, and you not only waste time, but recovery can be questionable.

If you have a backup, then you will be able to recreate the partition and restore data from it. It will be a lot faster and smoother compared to partition recovery. There are advantages of taking backup that includes

  • Avoiding data loss
  • Avoiding data overwriting
  • Improved performance
  • Reliable data and Improved reliability.

However, before that, let's take a look at the Backup Recovery Feature built into Windows. The tool creates a System Image for all the drives connected to the system. You can later use the Windows Advanced Recovery method to restore. The system offers a method to restore cloned partitions. The overall recovery method takes time and is cumbersome.

Compared to this, it is always good to use professional software such as EaseUS Todo Backup. It is a partition backup and recovery program, which can perform a backup automatically. It is specifically useful for those who deal with creating disk partitions on a regular basis. The backup will effectively save you from partition loss or partition data loss issues.

Step 1. Open EaseUS Todo Backup and choose "Create Backup" on the home page, click "Select backup contents".

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives.
