If you’ve accidentally deleted a partition, don’t panic—recovery is often possible. This guide covers step-by-step methods to restore accidentally deleted partitions with reliable tools on Windows 10 and 11. Perfect for beginners and experts alike.
Hi all, I hope you doing well. I would like to get help about an accident because I almost got a heart attack.
I wanted to format my laptop. Before that I sent all data do the Partition D: that was encrypted with Bitlocker. I also saved recovery key in any case. After that I booted with USB Windows 10 to format the drive deleted all partitions of the drive, when I made the killing mistake and deleted even partition D: by accident. So, the drive now just looks like "Unallocated" in Disk Management. I hope you feel my pain and I appreciate any advice or help about the problem I have. Honestly!

Accidentally deleting a partition on your computer can feel like a nightmare. Important files and programs may be lost instantly; what’s worse, if you delete the boot partition, your operating system might suddenly become corrupted, and Windows may label the freed-up space as "Unallocated."
So, is it impossible to retrieve data from an accidentally deleted partition? Of course not! Actually, the data in the partition is not immediately erased when the partition is deleted. Deleting a partition only removes the partition table, not the actual data itself. It is precisely for this reason that the system cannot access the data in the deleted partition.
You might still be skeptical—can I really recover accidentally deleted partition? The answer is a definite yes! As long as you use the right tools and methods, you can not only recover data from the deleted partition but also restore the deleted partition itself.
Accidentally deleting a partition doesn’t necessarily mean your data is lost forever. The files still exist on your drive until they are overwritten. That's why timely action is crucial. There’s another very important thing to note: stop using the drive immediately after a partition has been deleted. The recovery process typically involves three steps: recovering the data, recreating the partition, and optionally restoring the original partition structure.
The first and most important step is to recover your data before doing anything else. Creating a new partition or formatting the drive too soon can overwrite your lost files and make recovery much more difficult. If you have backed up the contents of this partition—whether using Windows' built-in backup tools or cloud backup tools like OneDrive—you can restore the data directly from the backup.
If you don’t have a backup, professional data recovery software will be your last resort. Since the partition table has been erased, Windows' built-in recovery tool, Windows File Recovery, will not work in this case. Third-party data recovery tools like MyRecover will be able to help you recover data from the deleted partition. It can scan the deleted partition for lost files and offer an opportunity to recover them.
